Early Thomas families

I have been gathering information on the Joseph Thomas family of Doran's Cove. Joseph came to the Cove in 1818 having been born in VA. in 1795.

Recently, I was told that his father and siblings had come from VA to Ky, to Tn and then to AL. Also that his father was named Samuel with brothers Robert, Samuel, Rubin, and others. Recently, I found a Rubin born in VA in 1780 living in Dist 19 in the 1850 Census. I was also told that a brother went to DeKalb county and settled.

Is anyone familiar with thes Thomas families?
