The fact that Siegfried's father's name is "David" makes it very probably that he is related to our John David Uibel – 1778-1843, buried at the Crosson Cemetery, Warren County, Ohio, about one mile west of Butlerville.
I have not attempted to research in more detail our ancestors from the Freistett Uibel clan. The attached family tree is an effort to list all descendants from John David Uibel, the first and oldest ancestor that any of us are aware in the United States. I apologize for any mistakes or errors and would be delighted to hear from anyone who has additional information or suggestions on this subject.
