I am from this Hughey line, but I don't have anything on Benjamin Barton's family. Cary Barton Hughey was born in
Dickson, Tn. This may be a lead for you.
George and Cary moved to Oklahoma for his health. I am not sure if he died in Oklahoma or Noxubee, Ms. Cary married Thomas Barton in Noxubee, Ms on Oct 8, 1844.
I have an extensive line on the Hughey family I will be glad to share. Mary firstname.lastname@example.org
