While I suspect that my roots stem originally from Switzerland, I have documents that indicate German relatives:
I am David Fankhauser, born in Fort Wayne, Indiana, 22 Nov 1941.
My father was John Harold Fankhauser, born 24 January 1916 in Fort Wayne, IN.
I have a birth certificate of my paternal grandfather Paul Friedrich Emil Fankhauser, born 11 July 1876 in Buchwald, Kreis Hirschberg, Rsgb. [Not fully sure of the meaning of items after Buchwald, but suspect it refers to a specific region of Germany.]
His Father (my great grandfather) was Muhlenpachter Andreas Fankhauser, evangelisch, wohnhaft in Buchwald Rsgb. [Ditto comments above. I am including words from the birth certificate that are probably not part of his actual name, but may be of significance in geneology. I do not know his birthdate.]
(My great grandmother was Sara Wegscheider, also from Buchwald, Germany, unknown birthday, but it was around 1850.)
If you know of Fankhausers either in Ft. Wayne, IN, or Buchwald, Germany, I would be interested.
