My father's mother's mother was Lydia McCoy (1875-1967) who was the daughter of Anderson "andrew" Boyd McCoy(1837- ?) and Elizabeth "betsy" Ann Rutherford (1836-1928). these names are on many databases on the "Worldconnect.rootsweb.com" site and shows alot more relations than I can type here.
My connection with the "Fued" family comes from Andrew McCoy's father Asa McCoy (1810- ?) who's sister Sarah married her first cousin Randolph McCoy who was the father of 16 children including the sons and daughter who the Hatfields murdered in 1883 and 1888.
