Don't know much about Washington Hullum, but found where he was in the Texas Rangers in 1860 at Palo Pinto County, Texas. I have my line back to William Hullum census 1790.Duke William Hullum married Martha Patsy Mcgehee in Louisa county Va. He also lived in ala. for a while. He was a Methodist Preacher for 51 years. Perform some marriages in Jefferson County Ala. His son Duke William Jr. was married there to a susan Brittain.
