Sarah: According to info I have, Sebastian came over on the ship Chance in 1764. I have his lineage all the way back to Hans Seibert in the 1600's.But, I can find no connection between Sebastian and his children and grandchildren to my Barnard. I believe Sebastian had a son named Bernhard and a grandson, also named Bernhard. Sebastian's Bernhard was Bernhard Bauman Seibert. If you want further info let me know.
