I have something similar in my husband's family. John Hardison, noted as born in TN and Anna Mefford, noted as born in KY. Daughter Mary Mehealy Hardison and I believe Amanda was a sister to her. Also have Gabriel (Gabe) as a brother. I believe there might have been others but I've just started looking and I haven't come up with firm proofs other than Mary's death certificate. I see census that might be right, but ... I would be interested to see how you've traced this group.
