I haven't been able to find anything beyond the 1870 census, either. I know that Thomas was in the Civil War and my dad said he remembered his dad telling him that Thomas got wounded in the war and that he walked with a limp as a result. Did you see the name of the first child on the census? I can't figure out what it is but I know that's not a name of any of the children that I'd ever heard of. Judging from the age, she was born the same year that Thomas and Harriett were married. I have no idea if this was his first marriage or not but he was around 40 when they wed so I'm thinking that he probably was married before. Please let me know if you find out anything. This has had me stumped for quite awhile now.
