Seeking info on "Granny". She supposedly migrated to Marion Cty TN with a child named David McNabb probably circa 1820. There seems to have been a strong tie between the two families since many McNabb documents were witnessed by McInturffs. There were also several marriages between McNabbs and McInturffs. "Granny" would have probably lived in Carter Cty. TN prior to the move to Marion Cty.
