Thank you so much for the information. I failed to mention that Lula Davis Poteet Campbell was my great grandmother. We didn't know she had a twin. Lula married Charles Campbell after William Poteet died. LH Campbell was one of their children. Evidently, my grandfather, A.H. Poteet was Williams's and Lula's only child to survive. I visited my great grandfather's and great grandmother's graves recently in Kellyville, Tx, as well as Frederick's and Mary Emma's, their children. It is very interesting to know they were only married a short time. Would you please tell me where you found this information, so I may research further?
