Hi Rebecca:I am glad that you found my posting.I have another posting and it is because of Ellis Cooper.He "THOUGHT" that he descends from Hans Dubendorffer Kueffer.I have been able to locate the Hans Dubendorffer in Switzerland.It is a surname.
What was written for all the Dubendorffers, and there was about six families at the Parish of Basserstarff.They were recorded because they were leaving their home area, and was going to take a ship to Carolina or Pennsylvania.That was their "SURNAME" it was not Kueffer.It is Dubendorffer.Kueffer is just a "nickname" plain and simple.
Here is what was listed for them:
Hans Dubendorffer, called Kueffer, the tailor's sonb. Feb 2, 1701.His wife Lisabeth Keller from the Parish Embrach.It list their four children:Rudolff, Hans George, (note: Hans George) Elsbeth, Katharina.It gives their birth year, the real story is Dubendorffer is a surname and all the names of the Dubendorffer families also has the " so called etc., etc., after their names all of them different nicknames, followed after their surname.
So Hans George in the above family is not the same George Cooper who was living in Hampshire Co., W.V.That is why Ellis Cooper's DNA matches the Coopers DNA, and the Kueffers. They come down from the children of Valentine and Vincent Kueffers (1737) who changed their name to Cooper when they came into VA., now W.V.
If you care to read this book it is on line.Full text of "List of Swiss emigrants in the eighteeth century to the Ameriacan Colonies"by Albert B,. FaustYou have to read down a long ways till you come to the names, there are thousands of names.The stories of their hardship is in this book.
So I believe that solves the Kueffer/Kufer/Keafer, etc., etc., and Coopers name change.My husbands line is John "Adam" Kiefer/Cooper whose DNA also matches the above Coopers, and I find him in MD., then Berkeley Co., and Jefferson Co., W.V.
