Stimulated by this post I did quite some research in the online copies of the original church records (https://www.be.ch/kirchenbuecher) and I could do quite some cleaning up (including some corrections) and adding of primary sources for Heinrich Zimmerman and his (ancestral) relatives. There was (and still is) some confusion and conflation. A few points to note:
- Zimmerman was spelled with only one 'n' at the time
- Heinrich's mother was named Anna Megert (not Anna Margaretha, no 'o' in her last name), this is still to be corrected.
- I could find and add some siblings for Heinrich Zimmerman, but I am quite sure that the two youngest "siblings" in WIkitree are not really his siblings; the correct parents for his youngest "brother" Hans are shown in his biography, but I cannot change it (project protected). I do not know who the correct parents for his second youngest "brother" Hans (John) are, because there is no christening of a Hans Zimmerman listed in the church records of Wattenwil in December 1702 (or thereabout).
