Never knew much about my moms family all’s I know is her dads name was Robert mitchel hack and his mother was Texie hack not sure if that is her birth name or not

Need more information. Dates, places etc.

"Grayson county Jt" Where is "Jt"? When did they live there? Do you have any other family names, Father, Mother, children?

Could be thousands of "Robert Hacks" in the world.
