Frances Evelina HARP, b 11 Feb 1853, Sauk County, Wisconsin, d 19 Oct 1940, Humboldt Co., CA. Married Thomas GRAHAM on 3 Jun 1881, St. Clair Co., MI. Frances had a son, George A., b 15 Oct 1872, MI, who used the surname of GRAHAM. Obviously, he was born before Frances & Thomas married so: 1) Did Frances have a son out of wedlock? or 2) Was Frances married to an unknown HARP and therefore would have had a different surname?
