Kate, where is your Charles Latham from? If he is from the Plymouth, Washington County area I may know who you're talking about. I'm not related,but have research interests in Washington County and have a little bit of info on him and his line (if we are talking about the same family).
Yes, that is the one, I'm helping an Aunt by marriage research her Latham family, her grandmother was Camille Latham, daughter of Lewis Charles, granddaughter of Charles, who married a Dr. Brown, who died early, they had 4 sons, I believe. :)
