Side note on Olivia (Lethy) Beckham:
I have not any confirming information on Lethy's parents, but as a result of researching the branches for this website, I noticed that Mr. C.L Beckham (age 45) and family lived in house #938 in the Giles Co, Tenn. 1850 census, while Andrew Knight and wife Lethe Beckham (age 20,) are listed in house #939. There is another Beckham family in house #937, but the head of household is Benj. Beckham (age36). I suppose either one could be Lethe's father. But Andrew Knight's first wife Drucilla Hardy had son Thomas J. (Jeff)Knight who was married to Sarah Ann Beckham, who appears to be in the 1850 census as daughter of C. L. Beckham with a wife named Mary Ann who was 27 at the time C.L. was 45. I wonder if Andrew's wife Lethy is actually the sister of Andrew's son's wife Sarah Ann, or perhaps she is half sister if Mr. C.L. Beckham had another wife before Mary Ann. I do not have a census page that shows Lethy in a parent's home. That would have to be 1830 or 1840, and I don't think names of children show on those. (spelling side note...in 1850 she is Lethe, in 1860 she is Lithy, and in 1880 she appears to be Letha (hard to read).
I am totally open to information or suggestions on the parentage of Lethy Beckham, wife of Andrew Knight.
