Thank you very much. This is very helpful. The grant I have is #543 so would come after the two you have mentioned. I don't have the full information, just the abstract from the North Carolina State Archives. I wanted to make sure I was in the right area before I went and ordered a copy. It is for Aaron Freeman, Burke County, North Carolina, USA Grant #543 200 acres on both sides of Lambeth's Creek; Issued 28 October 1782, entered 31 December 1779; Book 44, pg 254.
I will have to order the grant and see what other information it might have.
