I have a John Long b abt 1830 who married Sarah Luther. One of yours? I have been meaning to work on this because I think that estimated birth date is off considerably, Teh information I had was that their daughter Laura married Clark C Luther in Boone Co, IA. Sarah Luther was supposedly the daughter of Michael and Mary Nicholson Luther who were in Clay Co by 1830. Sarah was not in her father's hshld in 1850, and my opinion is that the person who estimated these ages probably did it without checking for census records for John Long. Any ideas?
