My grandfather, Andrew Jackson Allen had brothers, Thomas Nathaniel, b in Ga., Augustus L., Charles Lee, Authur A., James L., and George Lenard,I think but not positive all were born in Tx. He had sisters, Marchal M., Emma Pearl, Eva Malicia, and Willie Allion. Also as far as I know were born in Texas. However they were in Oklahoma later. Parents of these Allen's were William J. Allen b in Ga. 1866, (his father was born in Va.) and Serena Frances Taylor b in Ga.1868.The oldest son Thomas N. had a son Robert,bSept. 1893,in Tx. His siblings were Gracie and Gordon. I don't know if this will fall in with your Allens. It would thrill me no end if we could connect in some way.
