Patrick Carroll is probably the brother or cousin of Edward Carroll. Edward Carroll was baptized Edmond Carroll in Donoughmore Parish in the Diocese of Limerick, in County Limerick, Ireland, in 1835. The parish is southeast of Limerick Town on the eastern edge of the diocese. His parents were Thomas Carroll and Mary Carroll. An older brother David was born in 1832.

Baptismal records for Donoughmore Parish are not available before 1830. If they were, there might have been one for Patrick Carroll, who was born in 1828 (1826-1830, depending on source) and emigrated to Chicago long before Edward. When Edward and his family emigrated to Chicago in 1880, they moved in right next door to Patrick and his family on 14th Street.

In the 1880 census, Edward and Catherine Carroll lived next door to Patrick and Elizabeth Cagney Carroll, who lived at 681 14th Street. Patrick was a plasterer. Patrick and Elizabeth had immigrated from Ireland to Illinois about 20 years earlier because their oldest child was born in Illinois in 1859. Patrick Carroll was eight years older than Edward Carroll. They were probably brothers or cousins. In the 1870 census, Patrick and Elizabeth Carroll were living in Jefferson Township at the Cook County Poor House, called Dunning, where Patrick was the warden and Elizabeth was the matron. With ten other live-in employees, all Irish immigrants, Patrick and Elizabeth had charge of 424 residents: 279 paupers and 145 insane. Jefferson Township was annexed to Chicago in 1889. Dunning is now the Chicago Read Mental Health Center.

Patrick's 1894 obituary said that he was a Cook County commissioner and was three times elected County Commissioner. It also said he was a native of Ballineety, County Limerick, and came to America when a very young man settling in Chicago.

On August 5, 1894, Patrick Carroll, Edward's older brother or cousin, died at age 70. Patrick and Elizabeth Carroll lived down the street from Edward and Catherine Carroll on 14th Street.
