Does someone have access to the 1840 census for Montgomery County Ohio? I need a lookup for a John Martin b. 1804 PA m. to Eliza Brown b. 1806 PA. They would have (hopefully) a daughter named Lydia along with around 7 other children. I have been working on my Lydia Martin line for a very long time and I think I have a lead. John and Eliza are found in the 1850 census in Jackson Township with their 8 children. Lydia married Henry Hershey in 1848 so is not in the census with her parents (if these are them). Henry died in 1850 leaving Lydia with one child John Cornelius. I don't know if Henry was still alive at the time of the 1850 census.Lydia married George Adam in 1855. Any Help would be greatly appreciated.
