Bryan,
I did a little research on Littleberry McMillin, which leaves as many questions as I answered.
According to Traylor Russell's History of Titus Co. ,Tx
He and his wife were in Titus Co. 1n 1844. He was a doctor praticed in Snowhill and Mt. Pleasant, Tx.
He opened the first hotel in Mt. Pleasant in 1847.
He served in civil war.
He and his wife has no childern.
My question why an Arkansas unit and why not as a doctor? Just fruit for thought!
Mike
