Ava, Don't know if this will help it's just an example on one of my gentleman. It was a land grant State of North Carolina in Washington County date on it was 17th day of Aug. 1787. I found the deed in Washington Co., TN. When he sold this same piece of land to his son 2nd of May 1794 (I found it in Washington Co., TN) also but look at this description that is in the body of the deed. Between the two parties of Sullivan County in the Territory of the United States of America South of the River Ohio. Washington County took up all of what is now TN. I'd first look in Washington Co., then if wasn't there then I would got to what ever county was formed from that particular area. If you know they lived near a river or stream try to locate it on a map and try to pinpoint what county it was in the time frame you are looking. I'm sorry that I can't help you more. Wanda
