William King is my gg..grandfather. What I know is that Rhoda was in Denton County TX in the 1850 census, listed as widow with their 7 children, 5 of them born in Tennessee, one child has birth place unknown, and the youngest is born in Texas in 1844. William was born in South Carolina. But I haven't found anything about Rhoda Smith. I think she had a brother, Samuel K Smith, who was living with her and the children in 1850.
I would really like to find information on Rhoda. She seems like a very strong interesting woman. She is in the Denton County history book as "the widow with 7 children."
