Glad I could help. While you are asking your grandmother questions ask her for all she can tell you about Thomas' family, things like his brothers and sisters, other family members. Small clues can be a big help and while family legends should be taken with a grain of salt they can often have some truth to them. Hopefully she has lots of stories to tell. Some people use a recorder or video camera so they can preserve them first hand for future generations. Spike Lee, whose grandmother had lived to about 100, wishes he had asked her lots of questions of his family, but he didn't become interested until after she was gone.
