You might check Lewis post #7492 as there is a Frances Marion Lewis mentioned there. The researcher's grandmother is the Rebecca America Lewis mentioned, and another's is William Alexander that I have contacted as well.
My 'connection' is unproven at this date as I am attempting to link the mother of this family, Ruth Dunlap, to my own ggrandmother Adeline (sisters perhaps)
The researcher in the post has the family in Madison and Newton counties. As census go, there are blanks. I've also had Cemetary books checked, and nothing conclusive either, but perhaps we are not looking in the right places.
This Frances Marion in post mentioned could possably be the familiy you are looking for as the ch. were born between 1863 and 1885.
Perhaps we can collectively solve some riddles if we compare notes! Good luck in your search.
