Genetic genealogy can tell us about the deep ancestry of our ancestors and, in some case, which tribe or sept our ancestors came from. This story addresses the deep ancestry of Peter and Marilyn Carroll Biggins through the use of Y-chromosome DNA, tested by Family Tree DNA. Y-DNA is passed down from father to son, much like surnames. By testing a living male, we can learn about the deep ancestry of his paternal line. Testing can also help determine how closely two people are related.

Definitions

  • DNA. Deoxyribonucleic acid, a chemical consisting of a sequence of hundreds of millions of nucleotides found in the nuclei of cells. It contains the genetic information about an individual and is shaped like a double-stranded helix.
  • SNP. A Single Nucleotide Polymorphism, a mutation in the DNA that happens when a single nucleotide (A, T, G, or C) in the genome sequence is altered. A person has many SNPs that together create a unique DNA pattern for that individual. Family Tree DNA offers Big Y, which tests a large portion of the Y chromosome and identifies SNPs that have occurred down to the present time. SNPs occur randomly. The number of SNPs can vary a lot by tester. On average over a large population for a long time period, Big Y SNPs occur every 120 years.
  • Haplogroup. A group of similar haplotypes that share a common ancestor having the same SNP mutation Haplogroups are assigned letters of the alphabet, and refi nements consist of additional number and letter combinations.

Sean's and Peter's ancestors had farms across the road from each other in Will County, Illinois, southwest of Chicago.
The name Biggins comes from beag, the Irish for little. BY3164 Biggins DNA includes people named Beggan, Beaghen, Bigham, and Little. See Biggins/Beggan Irish Roots.
Sean's DNA matches Peter's, but it is not so close as to suggest that their ancestors were brothers or first cousins. Sean shares a SNP named FT17167 with Eric Began whose ancestor Michael Beggan was born in County Fermanagh in 1781. Peter does not have this SNP.
Z3008 is the DNA of The Three Collas, brothers who lived in 4th century Ulster. BY3164 descends from brother Colla Uais and his grandson Carthend. Carthend lived in County Derry in the 5th century on the Faughan River in an area that was later called a barony and named Tirkeeran. The name Tirkeeran comes from the Irish Tír Mhic Caoirthinn, which means land of Carthend. See: Z3000 The Three Collas and Faughan River

Paul has few DNA matches and none later then 400 BC. He matches men from England (Arnold, Bennett, Ozment, Phipps, Scott, Self, Wooten, Wright), Wales (Ellis, Price), Scotland (Armstrong, Reed, Russell), and Ireland (Moore). Many people with English names have Germanic origins. The term Anglo-Saxon is used by some historians to designate the Germanic tribes who invaded and settled the south and east of Britain from the early 5th century up to the Norman conquest in 1066. Our ancestor is from the far southern part of Old Saxony. See BY3323 Saxon

James' closest matches are people whose ancestors are from Scotland and Ireland. At some time between the 3rd and 18th centuries, his ancestors migrated from England to Germany.

Michael's DNA matches Ryan, O'Dwyer, Lee/Leary, Gorman, and Kennedy, as well as Carroll. These families descend from Breassal Breac who lived in Leinster around 200 or 100 BC. They settled in the 13th or 14th century in County Tipperary and County Limerick. DF27 DNA is the Gascon & Iberian branch of R-P312. See Y5058 Breassal Breac.

Michael's BY216377 DNA is associated with a group called Cenel Moain (FGC57780), a subset of Cenel Eoghain (S588), a subset of Northwest Irish (M222). Northwest Irish was originally identified in a Trinity College Study and said to be descended from Niall of the Nine Hostages, who lived in Ireland in the 4th/5th century. See: FGC57780 Cenel Moain

There may be a possible tester among descendants, but none has been identified yet. See Foy/Fee Irish Roots.

None. Looking for a distant Flannery cousin of Marilyn Most likely R-L151, P312, L21, M222 Flannery There may be a possible tester among descendants in Green County, Wisconsin, but none has been identified yet. Clan Flannery sponsors a Flannery DNA project at Family Tree DNA. Of the Flannerys from County Mayo who had tested their Y-chromosome DNA as of June 2012, all match up with a group called Northwest Irish. Northwest Irish was originally identified in a Trinity College Study. Two of these Northwest Irish have ancestors from the townland of Sarnaught in the civil parish of Aglish, which is nearby Derreenmanus: kits 36430 and 221086.

Byrne,

Null 425
Roger has "Isles-Scot DNA." His DNA matches closely with a Donald Austin Byrne (1934-2017), kit 338826 (see: Y-67 Genetic Distance), whose oldest known Byrne ancestor is Austin Thomas Byrne (1859-1934), born in Dublin.
He also matches closely with three testers named McGivern, which is associated with County Down. Byrne may be a form of McGivern.
Alistair Moffat and James F. Wilson in the 2011 book, The Scots: A Genetic Journey, say that "One of the most ancient Y lineages in Scotland is known as M284." They say it developed a later subset called L126 which is more common in Scotland. It is "also seen in Ulster, not only amongst plantation families (migrants from Scotland and elsewhere, most of whom arrived in the seventeenth century) but also in those of older pedigree. This shows an ancient connection across the North Channel."

L226
Leo shares Y5610 (1050 AD) with Conor Myles John O'Brien of Dromoland Castle who traces his ancestry back to Brian Boru. Brian Boru was born circa 940 in what is now County Clare and died in the Battle of Clontarf, north of Dublin, on April 23, 1014. See Irish Type III DNA. L226 DNA type also is called Dalcassian and Irish Type III. See DC782 Brian Boru DNA

Hopefully, we will learn more about our deep ancestry through testing of more family members.
