They settled in Richmond, IN but church records there say they went to Cincinnati for a while, later returned.Her gr. grandfather is Henry J. Tieman b. 1821 d. 1899.He married Charlotte Minetta Buscher b. 1833, d. 1913 in Richmond.I can't say if there is a connection.A brother of this Henry was William (Wilhelm) who m. marie Elise Duvelius. Their children were Katharina, Auguste, Wilhelm, Josephine Charlotte Lisette, and Dorothea Louise.They also were in Cincinnati for a while.Anoter Tiemann was Johann Heinrich who m. Marie Elisabeth Dinkelmann.Their children were Louise, Katharina, Marie, Wilhelm, Heinrich (says see church record book of th eGerman Lutheran Church in Cincinnati) and Adolph Heinrich b. 1 sep 1857.In Richmond, they apparently worshipped at "the old Lutheran parish).HOpe this gives you a little clue.
