We do not have any citations for Hans Jacob's birth, death, or parentage.
We also have significantly conflicting birth locations. Different managers have proposed:
- Oberscheinfeld, Neustadt (Aisch)-Bad Windsheim, Bavaria
- Oberarnbach, Neuburg-Schrobenhausen, Bavaria
- Oberarnbach, Kaiserslautern, Rhineland-Palatinate
A partially-cited tree for this family was found at https://www.familysearch.org/tree/person/L715-2M4 by Diana Collins, but none of the citations are relevant to these questions.
We also need to look at this potential merge for his wife and determine what is accurate: https://www.geni.com/merge/compare/6000000102742826069
Anna Margaretha Zimmer and Anna Margaretha Zimmer are the wife/wives in question.
Unfortunately I don't have the primary sources to check the information. Only a few partial transcriptions can currently be found at familysearch.org
Since all branches of the family lived in the region of what is now the state of Rhineland-Palatinate, it can be assumed that Oberarnach, Kaiserslautern, Rhineland-Palatinate is the correct place!

Parts of the current federal states of Rhineland-Palatinate and Baden-Wuerttemberg belonged to the Kingdom of Bavaria in the past, therefore unfortunately researchers without precise knowledge of the place and history are looking for appropriate places in today's state of Bavaria.
Unfortunately, such researchers also make the same mistake with the families in the Trump line.
They call as the place of birth or baptism of Johannes Sebastian Trump baptized 22.10.1699 Battenberg, Hesse or Battenberg, Germany.
The correct place of baptism was Battenberg (officially Battenberg (Pfalz) https://en.wikipedia.org/wiki/Battenberg,_Rhineland-Palatinate.
