Hi,
I am trying to link my g grandfather to records discovered on he and my ggrandmother on an Arkansas census. The names listed on the 1870 census are: Hock Thomas (later Hawkins Thomas) and wife Irene. Both seem to originate from Kentucky but, that is as far as I can get. Is there a method of finding out where in Kentucky that they were born?
I know I am grabbing for straws but since I have gotten this far in my search I find it difficult to leave it where it is.

Thanks in advance!
