Bill, I believe this is how I found Mary Polly DALTON. I went to FamilySearch.com and was looking for my Margaret DOTSON who married Thomas NASH. I found her and then her parents, Samuel Jr. DOTSON and Mary Polly DALTON (film #1985544) marriage about 1790 in Grainger, TN. Film #1985750 has Margaret DOTSON as being born about 1817 to parents Samuel Jr DODSON and Mary Polly DALTON. Interesting how on this film the childs surname is spelled differently. I have not seen these films personally but someday....... Cindy
