My Morgan was Dr. Richard Smith Morgan, b 1824 in Knoxville, married into the prominent Sneed family (Susan Edla Sneed) of Austin, TX in 1850 and had a boatload of children. Richard died in 1878. He had a sister named Jemima who married Elbert J Allen. Their parents were Joshua Morgan and Elizabeth Mary Smith. That's as far back as I was able to get on my Morgan side.
