In the 1850 Walker County, Alabama census one Millie Williams is found living with the Clark family. She is 54 years old, was born in South Carolina, and is listed as a spinster. The 1880 census for Walker County, Alabama shows a Henry living with wife Elezbeth and daughter Magret. Henry is shown to be 78 years old which would make his birth year as 1802. I feel sure that this is our Henry and have changed his and Elizabeth's death to "aft. 1880". Henry appears on the 1847 tax roll of Walker County.

Elizabeth was reportedly a Cherokee Indian. Martha Elizabeth's death certificate states that she was born in Alabama
