I am working on the Plaisance (Plasencia) line, the St. Pierre (Jean) line, the Williams line (William Riley), and several others. Any information would be appreciated. I will gladly return same. I have nearly 3000 names and have traced my son through his mother (viator, st. pierre, williams, etc) back to Adam and Eve, although I have not been able to completely verify this information. It appears there are at least 140 plus generations from him to Adam. The difficulty seems to be with ancestors of Charlemagne. It would seem this information would be accurate, but there are many, many discrepancies. Mark Plaisance Plais77@aol.com
