LYNCH AND McGRATH FAMILIES OF SULLIVAN COUNTY, NEW YORK
My wife's grandfather was George Henry Lynch, who was born in Liberty, Sullivan County, New York in 1890, a son of James J. Lynch and Mary Elizabeth McGrath. James, it appears, was born in New York in 1849, a son of Joseph and Ellen (McGrath) Lynch, and was in Sullivan County by 1870.
Mary Elizabeth McGrath was born in 1858 in Sullivan County, a daughter of Lawrence and Ann (Keough) McGrath. Lawrence and Ann had four daughters. Lawrence also had an older brother Patrick, who, with his wife Frances, had a large family including sons John J., William H., Lawrence and Reuben L. McGrath. Both the elder Lawrence and Patrick lived in Liberty, Sullivan County, but several of Patrick's children moved to near Livingston Manor, north of Liberty.
