“Jewish Ordinance” issued by Friedrich Wilhelm III [Prussia; Present-day Germany, Poland, Belgium]: “[…] Jews are prohibited from taking Christian first names. […]” [Researcher’s note: On March 23, 1841 a new ordinance was issued that said that Jews are only prohibited to take first names that refer to dogmas of the Christian church, such as Peter–as well as those who could be derived from the name of the “savior,” such as Christoph, Christian etc.]
