I have since found that Thomas G.M. SALLY and Sarah GIBSON married in Clinton Co OH, 14 Jun 1821. The 1830 Clinton Co OH, Clark twp reveals this to be apparently the same family as I had found in Shelby Co IN 1840 and 1850. Living nearby is a Thomas GIBSON family. One male is the age to be Sarah's brother, one male is the age to be their father. If anyone connects to this family, I would appreciate hearing from them.
