Heinrich Becker
I haven't been able to find a birth record for Johanna Sophia Becker, the wife of Georg Christoph Fett. All I know is that she was probably born in or before 1762 and that her father's name was Heinrich.
It's possible that she was the daughter of Johann Henrich Becker who married Susanna Margreta Bawel, the daughter of Peter Bawel, in Freinsheim 02 Nov 1756. This couple had at least one daughter, Susanna Christina Becker born 24 Nov 1757 and christened in Freinsheim 27 Nov 1757. I have no marriage record for her and no other birth records for children of Susanna Margareta and Johann Henrich.
I also don't have birth records for Johann Henrich Becker in Freinsheim or for Susanna Margreta Bawel or Peter Bawel at all. Johann Henrich may (or may not) have been either of two men:
Peter Bawel, the father of Susanna Margreta, may have been the Peter Bawel, son of Nickolaus, who married Anna Barbara Hoffman, daughter of Georg, in Freinsheim 19 Aug 1727. I have no further information on Peter, Nickolaus, Anna Barbara or Georg.
Although there certainly were other people named Becker who born, christened, married and/or buried in Freinsheim, I can't find any connections between them and Johanna Sophia Becker.
