Decree, issued by Jerome I, King of Westphalia [Present-day Germany]: “Art. 14. The marital status of Jews shall be clearly ascertained in front of the mayor or his deputy, beginning on May 1 of this year. […] Art. 15. Within three months from the publication of this decree, all Jews shall add a name to the name under which they are known, which is to become the distinguishing name of their family; they must register this name with the municipality of their residence, and neither they nor their children may change that name without our permission, under penalty of name-falsification. The mayors are to make sure that the Jews will neither adopt any names of cities, nor those of any prominent families.”
