Hi Helen, I also descend from Benedict Grossman & Betsey Seibert through their daughter Catherine who married Jacob Kissinger. I did not have a firm date of death for Betsey Seibert and you seem to have 1830. Could you please help as to where that came from and if you have a month and day? If you would like to exchange information I would be glad to. I have considerable info on the family. Take care. Jerry Thayer 311 Willow Oaks Blvd. Hampton, VA 23669-1531 HJThayer@aol.com
