Who were your Elizabeth's parents?

I suspect from various circumstantial evidence that Thomas Moore, son of Calvin & Seatta Moore, is my Grandma Belle Moore [Mary Belle] Steele's father. My Thomas stated on his WWI draft card that he was born in Floyd County KY in 1888. Grandma Belle had a relation, cousin we think, named Gomer Moore. Calvin also had a son John who had a son Gomer....Calvin's Thomas was born in 1888. I need some documentary proof, though.
I am looking for a death certificate [1925] and have been unable to locate one for Tom. Tom & Belle looked Indian, black hair & eyes, dark complexion, and what I have heard is that there was Indian..... no documentary evidence.

From others research, primarily Jack Goins, it looks like John & Sally Moore, grandparents of Calvin, lived in the NC area of the "Goinstown Indians" before migrating to Floyd County Kentucky. This is as far as I have gotten so far.
