William Perry Manly would be a 1st cousin to my g-grandfather Melvin Manly. William Perry's father was Garlington Manly, mother Rachel Carmack. Garlington was brother (or at least half-brother, we're not sure on that one yet) to William Manly. Their parents were William Manly (Sr) and Elizabeth Nickels (Garlington may have had a mother named Sarah who died between SC and IN - we're not sure on this one). Garlington is listed on census records and in probate records as a sibling.
Would love to have an e-version of the picture, although I would have no way of confirming any information.
I have all three marriages in my files, though no exact marriage dates.
