Louis Joseph Kohler
He was illegitimate which, apparently, did not carry the stigma at that time that it carries today, because the Revolution undermined religious norms. The baptism record of his son Francois Joseph Kohler states that he (Joesph Kohler) was a bachelor and surgeon from Molsheim. The profession of surgeon was different from doctor of medicine. A surgeons were located mostly in larger towns, not villages, and places where regiments were staying ; they often followed the armies. The surgeon is called to smaller places but generally resides in cities like Molsheim or Bischwiller. Incidentally, in a name like Louis Joseph Kohler, the first name (Louis) came from the godfather and was later dropped.
