I've set up a Seymour Immigration web site. It contains family trees (with attached GEDCOM files) for two American immigrant Seymours: Richard (c.1639) and Felix (c.1725).
Take a look! And, if you have anything to offer, please let me know. My
goal is to document as many Seymour immigrants as possible. If your Seymour
line doesn't connect to either of these, I'd love to get your database!http://www.aracnet.com/~jseymour
