Thanks for your help - and yes I was mistaken on John's date of death. I think he passed shortly after the 1870 census in Texas. There is a possibility that they were in Mississippi for the 1860 census. We're not positive when they made the move from AL to TX. Family history says they took a boat down the Mississippi and arrived in New Orleans where they joined a wagon train going to Texas.
Is there by chance an 1840 census? I think if I could get an 1840 census I could link the Basket girls back to William Basket.
