I sure am hoping you find something ! There are a few of us that have been searching for a George Poff in that time frame for a while!!!
We have a Thomas Bueford Poff born 1826 in Harlan Co., Ky.. From a family bible, it says his fathers name was George. There is a George in Harlan Co. Ky. census for 1830, but not after.We were tracking the George you described.
Just speculation but we think he must be a son or grandson of George Poff & Anna Merchant.But at the sites I have found for this family, no one has anything on George Jr..
Do you have any children for your George ? Please say yes !?!?
Can contact me at :email@example.com
Will keep my fingers crossed !
