Ely Carroll

This page is about the DNA of an ancient Irish clan called Ely Carroll. This is a name that surfaced in the Middle Ages. Ely is an anglicized form of Éile, a territory in Tipperary and Offaly. This clan was originally known as Clan Cian or Ciannachta, going back to a man named Cian in the 4th century.

Famous persons descended from this clan in modern times are:

• Charles Carroll of Carrollton, 1737-1832, a signer of the American Declaration of Independence in 1776.
• John Lee Carroll, 1830-1911, great grandson of Charles Carroll of Carrollton, was governor of Maryland from 1876 to 1880
• Daniel Carroll of Duddington, 1764-1849, built a home for himself in 1791 which was torn down by Pierre L’Enfant to build the U.S. Capitol
• Charles Carroll of Bellevue, 1767-1823, was friends with president James Madison and his wife Dolly. During the War of 1812, he went to the White House and saved the portrait of President George Washington for Dolly. He then took her to his home Bellevue in Georgetown, Washington, DC, until she could be reunited with the President.
• Daniel Carroll II of Rock Creek, 1730-1796, was one of the Founding Fathers of the United States. He supported the American Revolution, served in the Confederation Congress, was a delegate to the Philadelphia Convention of 1787 which wrote the Constitution, and was a U.S. Representative in the First Congress.
• John Carroll, S.J., 1735-1815, was the first Roman Catholic bishop in the United States. He was a founder of Georgetown University and Georgetown Preparatory School.

Birr Castle

Birr Castle is a large castle in the town of Birr in County Offaly, Ireland. St. Brendan the Elder (not the Navigator) founded a monastery in Birr about 540, serving as its abbot. There has been a castle on the site since 1170, and from the 14th to the 17th century the O'Carroll family ruled from here over an area known as "Ely O'Carroll." According to the Birr Historical Society, "the present castle building was developed on the site of a previous tower house and bawn probably built by the Anglo-Normans. It subsequently became an Ely O'Carroll stronghold. It was demolished in 1778 and all trace of it has disappeared in the terraces and herbaceous borders."

Birr Castle today.

The castle above was not the original castle. Genetic genealogist Maurice Gleeson forwarded an article in The Irish Times of August 6, 2018: "Archaeologists and historians have been turning up unusual finds across the country thanks to the heatwave, including . . . . impressions of the Ely O’Carroll “Black Castle.”

“The Black Castle would have been more or less the headquarters of the O’Carrolls,” explained Mr Kennedy. He said most of the old castle was long gone. “Where the main hall of the castle is today was originally the gate.”

"The Black Castle was held by the O’Carrolls until the 1580s when it was sold to the Ormond Butlers. The castle fell into ruin before it was granted to the Parsons family by James I in 1620.

"While it was known the old castle had been located on the grounds of the existing castle, the exact location has only now been revealed thanks to the weather."

Charles Carroll of Carrollton

In 2008, a descendant of Charles Carroll of Carrollton joined the Carroll DNA Project at Family Tree DNA and had his Y-chromosome DNA tested. His DNA is published along side other Carrolls on the Carroll DNA Project Results page at FTDNA. He is kit 112378.

Y-DNA is handed down male to male like traditional surnames. So, his DNA is the same as his ancestor, Charles Carroll of Carrollton. Other Carrolls in the Carroll surname DNA Project could now see whether their DNA matched up. About 10% of the Carrolls in the Carroll surname project match up.

Signature of Charles Carroll of Carrrollton on the Declaration of Independence, 1776.

Charles Carroll of Carrollton is important because he was a signer of the Declaration of Independence in 1776. He was the only Roman Catholic to sign, and he was the sole surviving signer following the deaths of John Adams and Thomas Jefferson on July 4, 1826.

The pedigree of Charles Carroll of Carrollton, and his descendant who has tested his DNA, goes back to 4th century Ireland. And the descendant's DNA matches up with the DNA of men with surnames that are supposed to be related based on ancient pedigrees.

Ancient Pedigree of Kits 112378 and 738989

Google Books has made the 1892 edition available online: Volume I and Volume II. The University of Pittsburgh Library System has made the 1892 edition available online as a PDF file or Ebook: Volume I and Volume II. Library Ireland has made a transcript of Volume I available online.

Years 1150 to 1550. The October 1883 issue of the Journal of the Royal Historical and Archaeological Association of Ireland contains an article by Frederick John O'Carroll entitled "True Version of the Pedigree of Carroll of Carrollton." The article takes the above pedigree from Fionn, King of Ely, who was slain 1205, up to Donough, who lived around 1550.

Years 1550 to the present. In the year 2000, The University of North Crolina Press published a book that includes a pedigree of Charles Carroll of Carrollton. The author is Ronald Huffman, professor of history at the College of William and Mary. The title is Princes of Ireland, Planters of Maryland: A Carroll Saga, 1500-1782. Below are pedigrees taken from that book, with the addition of descendants down to two Y-DNA testers: kits 112378 and 738989. (Generation numbers have been added to facilitate reference to the more distant pedigrees provided above.)

Testers with kits 112378 and 738989 have a genetic distance of 3 based on 67 STR markers. They have not done the Big Y test, but both are predicted to have Ely Carroll SNPs based on their STRs and matches and the Big Y results of Linville (Carroll) kit 23133 and Lee kit 54646: Z16291, Z16284, Z16289, BY2009, and BY20010.

Ely Carroll DNA Project – Testing

The test results evaluated here all came from Family Tree DNA. Only 67 or 111 markers tested are included here because those tests include the 66th marker, 492, which is crucial to the analysis.

If you are a male with the name of an Ely Carroll descendant, you may benefit from participating in the Ely Carroll DNA Project at Family Tree DNA.

Family Tree DNA has the largest DNA database in the field. For a look inside the FTDNA lab, see "A Visit to Family Tree DNA's State-of-the-Art Lab," written by Cece Moore in February 2013 based on a tour in November 2012.

The Ely Carroll DNA Project was started in January 2011. The project is designed to attract Ely Carroll descendants, encourage upgrades to the 67-marker test, and promote Ely Carroll research.

You can participate in our project as well as a project specifically set up for your surname. There is no additional cost for being part of two projects.

By testing the Y-chromosome DNA, males can determine the origin of their paternal line. Note that the Y-chromosome DNA strictly checks the paternal line, with no influence of any females along that line. Females do not receive the Y-chromosome, and therefore females cannot be tested for the paternal line. If you are a female and would like to know about your paternal line, you would have to find a brother or a male relative from that line willing to be tested.

The two swabs and scraper tubes in the FTDNA Kit. For more on how it's done, see "DNA Collection Method" by Dave Dorsey.

Y-chromosome DNA goes back male to male like traditional surnames.

You sign up online for FTDNA and they deduct the cost from your credit card. They send you in the mail a kit containing two scrapers that you use to swab the inside of your cheeks in four-hour intervals. You return the scrapers in receptacles and mailer provided in the kit. You get final results on line two months later.

If you decide to have your DNA tested, you should choose the 67 or 111 markers. The lesser tests of 12, 25, or 37 markers do not include marker 492, which is key to verifying a match with Ely Carroll descendants.

Most names have multiple origins. For example, there are Carrolls with 25 different types of DNA. For this reason, your results may show that your DNA does not match the Ely Carroll DNA, which will lead you in a different ancestry direction.

Ely Carroll DNA Database – Modal DNA and Key Markers

The study of Ely carroll DNA began with a preliminary modal DNA for relatively small number of people who had Ely Carroll names and DNA similar. This modal DNA evolved into a modal DNA, based on data from the Ely Carroll DNA Project, under the user ID of TG7S3 at Ysearch. This TG7S3 Ely Carroll Modal DNA is now the one used in this study. Since June 2009 the database of people with Ely Carroll DNA has expanded and the modal has been recomputed. Each time, the modal has remained the same.

A reference group was put together of people who do not have the Ely Carroll DNA. This group helps to understand the uniqueness of Ely Carroll DNA, such as marker 492=11.

Ely Carroll DNA Database – Genetic Distance

Actual calculations were made using the FTDNA 111 Mode BETA version of the McGee Utility. Input to the utility consists of the DNA of the participants from the Source Data.

As of September 21, 2017, there were 118 people with 67 markers included in the Ely Carroll database. They have been included because their DNA has been found to match fairly closely with Ely Carroll Modal DNA. Three out of four were included in the Ely Carroll DNA Project at Family Tree DNA. The rest have been obtained by searching surname studies at FTDNA and through the use of Ysearch.

Table of Genetic Distances. The table below shows the 67-marker genetic distances for the 110 people in the database between each one and the modal.

• The 118 genetic distances from the modal range from 1 to 11 (average: 5.7).
• The genetic distances among the participants range from 0 to 18 (average: 9.1).

Historical Surnames

The identification of Ely Carroll DNA rests on the pedigree of the person with kit 112378 who is descended from Charles carroll of Carrollton. It also rests upon the similarity between a set of related names in ancient pedigrees and a set of names among men with matching DNA. See A Coincidence of Names.

Many people with Ely Carroll DNA do not have historical surnames. The major names are: Purcell, Springer, Tracey. Ely Carroll DNA has not yet been found for several historical Ely Carroll names: Corcoran, Healy, O'Gara/O'Hara.

Many people do not know where their patronymic ancestor came from, which is not uncommon. Only a small number of those tested live in Ireland. Most live in America. Many of those have resorted to DNA testing for the very reason that they do not know where there ancestors came from when the emigrated to America.

The Ely Carroll database includes some people with non-Irish sounding names. It includes some people who are related to each other. It includes surnames where there is only one representative.

Some names historically associated with Ely Carroll, like Healy, O'Hara/O'Gara, and Corcoran, are not found in the study. There are a number of good reasons.

• Only a small number of people have had their DNA tested thus far.
• Many who have had their DNA tested have tested only 12, 25, or 37 markers rather than the 67 required for this study.
• Some people have been tested by an organization other than Family Tree DNA.
• Some people may have lost their name because an ancestor changed his name or was adopted.
• Ancient pedigrees probably included some surnames of people who were not really Ely Carroll descendants.

There are many people in the Ely Carroll database that do not have historical Ely Carroll surnames. There are a number of good reasons.

• The historical lists of Ely Carroll descendants were incomplete.
• The name is on an historical list of Ely Carroll descendants but we have not found it yet.
• In early Irish history there was the concept of “fostering,” where two powerful tribal leaders would place their infant son with the other family to seal a defensive alliance. It is likely that some of these sons took on the tribal name of the family with whom they were placed.
• There was a name change by an ancestor.
• They or an ancestor were adopted.

L21 and DF21 SNPs

All Ely Carroll project members who have tested for the L21 SNP (single-nucleotide polymorphism) have tested positive. L21 was discovered in October 2008. People with the L21 SNP are said to be members of the R1b1a2a1a1b4 haplogroup. As groups of scientists discover SNPs, they are named for the research lab and the order in which they are found. The L in L21 indicates that it was found at the Family Tree DNA Genomic Research Center in Houston, Texas. The L stands for Leo Little who did much pioneering work in genetic genealogy and who died in 2008. (L21 is known as S145 in some testing organizations.)

The L21 SNP is estimated to be 4,000 years old. It is sometimes referred to as a "Celtic" SNP. In their 2011 book The Scots, A Genetic Journey, Alistair Moffat and James F. Wilson say L21 "could be said to be the most emphatic signal of the Celtic language speakers of the British Isles. It is found in England, Wales, Scotland and Ireland and it is almost certainly characteristic of those farming communities who may have spoken early forms of Celtic languages in the centuries around 2,000 BC."

L21 SNP Tree, Including DF21

Ely Carroll participants also have tested positive for the DF21 SNP, which is downstream of L21. The first Ely Carroll member tested positive for DF21 in August 2011. As of October 13, 13 of 48 members of the Ely Carroll project have tested for DF21 and all have tested positive. This further narrows the haplogroup for Ely Carroll descendants. All Ely Carroll descendants are expected to have the DF21 SNP. Other groups also have the DF21 SNP--perhaps 10 percent of all those with the L21 SNP. The DF21 SNP is estimated to be 4700 years old (see Rathlin Man 1). It was discovered by an anonymous researcher using publicly available full-genome-sequence data, including the 1000 Genomes Project data. The DF in DF21 is taken from DNA-Forums.org, a now-defunct genetic genealogy community. (DF21 is known as S192 in some testing organizations.)

DF21 SNP Tree, Including Ely Carroll

Ely Carroll participants are urged to join the L21 project and DF21 project at FTDNA. The DF21 project has been set up by David Reynolds for people who have tested positive for the DF21 SNP or are interested in ordering the test.

The L21 Yahoo Group has been set up to serve as a forum for those interested in DF21 and other SNPs downstream of L21. We also have a Ely Carroll Yahoo Group has been set up to serve as a forum for those interested specifically in Ely Carroll DNA.

In April 2014, Alex Williamson identifed new Y-chromosome SNPs for Ely Carroll testers downstream of DF21. The SNPs came from a new product called BIG Y, which looks at more than 1/3 of the testable portion of the Y chromosome.

Past efforts to find an Ely Carroll SNP have failed. In 2012-13, Linville (23133) and Carroll (283359) participated in Geno 2.0 at National Geographic (tested by FTDNA). But no SNPs were found downstream of DF21.

Without BIG Y, we identified Ely Carroll DNA with two key marker values: 390=25 and 492=11. The first became known when FTDNA started. The second became known in 2006 when 67 markers became available. We also have Ely Carroll modal DNA, which was started in 2010. And, since 2012, we know that all Ely Carrolls have the DF21 SNP. We are thankful for all that. But we knew it would be better if we had a SNP downstream of DF21 that specifically identified Ely Carroll DNA. BIG Y has done that.

Table of Contents     

BIG Y

1. SNPs. SNPs (e.g., Z16291) are single nucleotide polymorphisms, or mutations, found on the Y chromosome of male BIG Y testers. SNPs that are inherited by two or more testers allow the creation of tree branches with named SNPs.
2. Alex's Big Tree. Click on a SNP in the table below to see the SNP on Alex Williamson's Big Tree, including tester names and kit numbers, the block of SNPs in which the SNP is included, and the estimated year.
3. Testers. After each SNP are the names of Big Y testers whose DNA named the SNP.
4. Subgroup. Click on the subgroup after a SNP to see the names of Big Y testers (y) and other members who are predicted to have the SNP. The subgroups are based on surname, genetic distance among group members, and unique STRs. Shown is a matrix of the the 67-STR genetic distances among the members based on the McGee Utility.
5. Year. The year shown after a SNP is the estimated year of the most recent SNP in the block of SNPs in which the SNP occurs. A block of SNPs consists of one or more SNPs possessed by all testers who descend from the block. The order of a block's SNPs is unknown. The number of SNPs affects the year estimate. Estimates are made by Alex Williamson using a method developed by Iain McDonald. Estimates are necessarily very rough. Click on the SNP block in Alex's Big Tree to see information about the estimate.
6. Unique STRs. Shown after some SNPs are STRs (short tandem repeats) that are unique for that SNP.

Ely Carroll BIG Y SNP Tree

About the Tree. The tree shows Y-chromosome SNPs of Ely Carroll BIG Y testers. BIG Y is a Y-chromosome testing program offered by Family Tree DNA since 2014. It identifies a man's SNPs (single nucleotide polymorphisms) and compares those SNPs with other men it has tested. The Ely Carroll BIG Y SNP Tree includes the SNPs of all Ely Carroll members who have been tested under the Family Tree DNA BIG Y program, which tests a large part of the Y-chromosome. The tree is based on Alex Williamson's Big Tree. Ely Carroll can be found on the Z16291 portion of his Big Tree. Testers have downloaded their raw results from their FTDNA homepage. The raw results are then uploaded to the Y-DNA Data Warehouse (prior to October 2017, Big Y file in the L21 Yahoo Group). Testers agree to making their results public on the Big Tree. Alex compares a tester's SNPs with other testers and puts him on his Big Tree based on shared SNPs. We owe Alex Williamson a debt of gratitude for producing his Big Tree and including us in it. Alex has the DNA of a group called the Little Scottish Cluster.

Mike Walsh maintans a tree for Z16291 as part of his R1b Haplotree.

FTDNA maintans a tree for Z16291 as part of its Haplotree & SNPs, which is accessible by each tester from his homepage at FTDNA.

For a summary of BIG Y, see the FTDNA Big Y Q&A.

SNPs are either named or unnamed.

• Unnamed SNPs have a 7 or 8 digit number based on their position on the Build 37 human reference genome. The letters indicate the nature of the mutation, e.g. from C to T.
• Named SNPs have been given a short name to make them easieer to remember. If you wave over them with your cursor, you will see the longer SNP designation. SNP names start with letters.
  • "A" SNPs were named by Thomas Krahn. See the YSEQ SNP Index.
  • "BY" SNPs were found with Big Y at Family Tree DNA. See the BY SNP Index.
  • "F" SNPs were named by Li Jin at Fudan University in China.
  • "FGC" SNPs were named by Full Genomes Corporation of Virginia and Maryland.
  • "L" SNPs were named by Thomas Krahn in honor of the late Leo Little.
  • "M" SNPs were named by Peter Underhill, Ph.D., of Stanford University.
  • "PF" SNPs were named by Paolo Francalacci at the Università di Sassari in Italy.
  • "S" SNPs were named by James F. Wilson, D.Phil. at Edinburgh University.
  • "Y" SNPs were named by the YFull Team using data from the 1000 Genomes Project.
  • "Z" SNPs were assigned by the Community.

Analysis of L21 and DF21 DNA

The genetic distances among the 67-marker modal DNAs of the subgroups listed above range between 11 and 20 as shown in the following table. Calculations were made using the FTDNA 111 Mode BETA version of the McGee Utility. The method of computing genetic distance is the hybrid mutation model. If a marker has a null value for one person and a positive value for another, the marker is ignored. So, the genetic distances between the Clan Colla modal and other modals ignore marker 425 and are a little low. As an example, see Colla Versus Niall DNA.

Deep Ancestry

Patrick McMahon analyzed the geographic distribution of the members of the L21 project at FTDNA in January 2011 and made the following observation.

Assuming today's testers are a random sample, these results support the views put forward by many that the L21 SNP occurred somewhere north of the Alps (about 4,000 years ago) and the L21 population drifted Northwest over time concentrating in the western fringes of the British Isles mainly in Ireland. North of the Alps would most likely be Germany or France where the original (presumed) high numbers would over time be replaced by further waves of migrants or simply driven North by more advanced civilisations.

How they made their way to Ireland is open to conjecture. The shortest sea journey then (3,000 to 4,000 years ago) as now would be from France to Southern England. However, they could have made their way directly to Ireland from Brittany (or via Cornwall or Wales). The figures support the view that there was no significant migration towards the Eastern parts of Europe and only minor ones to Scandinavia and Spain with the main thrust through Northern France to Britain and Ireland. Archaeologists have termed these peoples (and the proto-Collas are part of this population) as 'Bronze-age' Britons.

For a good presentation of the origins, age, spread, and ethnic association of Europeans see The Peopling of Europe and Eupedia. Following is a haplogroup timeline taken from Eupedia. "ybp" is years before the present.
