I've been using census records to trace Hornback/Hornbeck family as I tie to a female side in the early 1800's. I have Addie's family traced to her grandmother Martha "Patsey Connell who married Abram/Abraham Hornback in Champaign Co OH 28 Mar 1822. Martha's parents were Angel and Martha Fleming Connell. Martha Connell Hornback and one of my ancestors were siblings. You can find a quite a bit about Abraham Hornback in Winterset, Madison Co IA. I have a family tree posted on ancestry with these names. Winterset is an important research place for this family.
