According to the 1880 and 1900 censuses, Perry C. Gallagher was born April 1845 in Ohio; both his parents were born in PA. In the 1880 census he is Perry C. Gallagher; in 1900 he is Cornelius Galliher (sic), so I surmise that his full name was Perry Cornelius Gallagher. He lived near Graysville in Monroe County, Ohio, and had ten or eleven children, among them a son named Everett, born in 1879.
I believe that Everett Gallagher was the father of one Cornelius Everett "Neil" Gallagher, born out of wedlock in 1909 to Sarah "Sadie" McNiece, daughter of William McNiece, who lived just west of Graysville. The family story is that Neil's father wanted to marry Sadie, but she refused to leave her "Mam" (who appears to have been not right in the head).
Neil left home as a teenager and changed his name to Neil Everett McNeice (reversing the 'e' and 'i' for some reason); on his application for a Social Security number, he claimed that his father was 'unknown'. This was a complete falsehood, since in 1920, when he was eleven, the census recorded him in the McNiece household as Cornelius Gallagher. By the 1950's Neil was prospecting for uranium in Wyoming and struck it rich; he sold his "Lucky Mc" mine to the government for millions of dollars.
There was another Gallagher connection to the McNiece family: In the 1880 census, Sadie McNiece's uncle Alexander McNiece has a 4-year-old Charles Gallagher living with him and his wife Elizabeth; Charles is described as their adopted son. They had no children of their own, so I'm wondering what became of Charles Gallagher.
I suspect that both Perry Cornelius Gallagher and Charles Gallagher are related to the Gallaghers of Butler Co. PA, some of whom settled in Guernsey and Noble Counties adjacent to Monroe County. The name "Cornelius" occurs often in these families. Some say they came from County Donegal, Ireland, others say County Meath. I would like to know more about them. My mother was Cornelius Everett Gallagher McNeice's cousin, and I remember visiting him and his wife in Wyoming in 1951 and seeing his ore samples and Geiger counter.
