I'm also looking for ancestors in those areas. A. B. Heckman had several daughters: Emma, Margaret, Francis Marion, not sure if there were any sons. Emma married Jackson Richardson, and had a child who married a Guy Shoemaker. I believe one of the daughters married a Charles Davenport. Francis married my great-grandfather, William T. Riley.
If you get any information on this family I would appreciate sharing what I have with you.
