I understand that your main interest is in the Bean family, however, I'm telling you that I have the same person down as being the wife of someone else and it is very well documented from several Censuses and other records. It is possible that there are two Lettitia Vermillions in the same place at the same time, but it would not seem to be a real common name. It is possible that one of us is wrong about her marriage to one of these men, though I say again that the marriage to James Louderback, is very well documented. MOST INTERESTING, however, is the possiblity that she married twice. I know she was married to James Louderback during the 1830s and 40s if not beyond. Could she have originally married Moses and, perhaps, remarried to James after his death? This raises the possiblity that some of the children listed for her as Louderbacks might actually have been Beans.
IF they are the same person, I have quite a bit on her ancestry that might be of use to you. Do you have anything else on the one who married Moses Bean?
