Hi, I really can't answer your question as to whether Sarah Thomas was an orphan. Her father's name was John Thomas. She was born Sarah Ann Thomas, 1854 near Ursa, Adams Co., IL and died 1930, Lewis Co., MO. She married Erastus Bozarth, 16 Sept 1875 in Lewis Co., MO. They had two children Leslie b. 1882 and Loretta Pearl, b. 12 March 1892, died 25 Jan 1974, married 25 Oct 1911, Elmer Logan. Are you a descendant of either of these children. If you e-mail me I can give you the name of a lady that might be able to help you.
