I'm following up my own post with an update: I found a listing for Cynthia Peeples in the 1860 state census for Choctaw County. Apparently James O. Peeples was already dead by this time. Cynthia was listed as head of household containing 2 females, 4 males and no slaves. She is living a few households away from her sister, Polly Peacock. Cynthia is not enumerated on the 1860 federal census, however, although Polly is. I would like any information on the children of James Oliver Peeples and Cynthia Peacock Peeples other than James O. Peeples (my line) and Joshua Sanford Peeples. These two lines are fairly well documented, but I don't find records for the others: Georgia, Julia, Jackson, Harris, Winston, Joshua and Charlotte Francis.
