there is a little more information but this is the basic information. Do you have birth, death or marriage records of any of these people, also looking for land grants, war records, any records would be welcome. I am also putting together a book for my children and am not finding a point to stop. I hope your father enjoyed his present. I'm sure he appreciated your interest and effort.
