Thomas Henderson's brothers?

I think a new clue has popped up on my obsessive search to get my line ironed out :)

We know that Thomas Henderson, the pioneer... had land purchased in Greene County, eventually becamse Hawkins and some land broke off to become Grainger,etc...

Thomas' land stayed in the same area. North of the Holston River.

and then John, he sells land to George Henderson. on North of Holston River in 1812.

an he also purchase land in 1793 on the North of Holston River.

Are they related? Hell yes they are!

how?

Father and son? or ........ Brothers? More clues will come up as I look at the land deeds for John Henderson. If Thomas sold some land to John, that means he is the son of Thomas.

now where will that place George now? Either John is the father of George OR George and John are brothers.

to be continued......
