Jim: I also got that info from another source and it agrees with the 1772 date. I would like to say in touch with you since we are both interested in the Seibert clan. I have put together a database with about 576 Seibert ancestors in it going back to old Hans Seubert. I think I have finally found the connection between John Sebastian and my line of Syberts. Send me your e-mail address to my e-mail address if you can.
