My Great-Great Grandfather was John Henry Roof of Indiana County Pennsylvania. I think his father was Jacob Roof of same county, Mahoning Twp. I have his will dated Feb. 14, 1842. In it he mentions a son, Washington (no George), however my GG Grandfather, John Henry, had a son named George Washington, born 7-6-1850 and died 4-21-1922 in same county. Wonder if there is some connection?
