Thank you David...this is indeed the family..
In 1843 Lucy Hart Nelson applied for a widowers pension as a result of John Nelsons service in the Revolution. John and Lucy are the grandparents of Mary Hathcock Hart. Lucy Hart Nelson was born in 1772 in Cumberland County North Carolina. Lucy and John were married in 1786. In the petition James Hart, the brother of Lucy Hart Nelson attests to the fact he was present at their marriage. Now, the James Hart of Coffee County and Hickory County wasn't born until around 1800. So, I'm wondering who the James Hart (brother of Lucy)is? The Father of my James Hart? Uncle? etc. The data I find on Lucy Hart Nelson says her parents were William and Anna Hart. So, without some oral history from the family,it is difficult to document the data.
