I don't know about your people; but wished I did. I only know about Dorothea Christina Zibellen's DOB 1776 and her father was Johann Friedr. Zibell and I don't have his DOB but I presume it was abt. 1756. He was from Bramstaedt. Let me know if this sounds familiar to anyone out there. Keep me in your files for future reference. Thanks Jeannine
