Good morning, Yes I did find this also, but its always nice to have your info checked and verified with someone else. I also thought that John was probably his son, and I am not sure but he most likely could be living with a married child. Moses Davis married Mildred in Greenup co. around 1829 I believe.
THe story was that Moses was born in Mason co. Ky. and moved to Rush co. Indiana with his parents but decided to move back to KY. after all he had no reason not to. James Davis was however another story. LOL He was caught with another mans wife, they fought he won, but the sheriff ordered him to leave Ky and not come back hence the move to Rush co. Indiana. I don't know how true the story was, but you know family folklore. This is what my husband grandmother told me.
So Moses is there in 1840 and married to Mildred by then.
But Moses could very well have been born in either Mason or Greenup, considering that when they became counites.
James Gibbs might not have moved at all in all those years, county lines just kept moving. I had a person once tell me that his uncle lived on the same farm all his life but lived in 4 different counties while alive. lol And from what I understand about Moses he also lived in the same area all his life once he came back to KY from Indiana.
So his farm probably sat in the same position just county lines kept changing. So its hard telling exactly where James might have been in 1840. the tax records for that year might help but I don't know how to find those.
