Ordinance, issued by Friedrich Franz, Hereditary Grand Duke of Mecklenburg-Schwerin [Present-day Germany]: “V. Resident Jews are obligated to always use German or another living language for their business ledgers, contracts and wills, under penalty of being null and void; they shall, on the other hand, never use Yiddish; and their names may not be signed in any handwriting other than German or Latin. XII. Marriages between Christians and Jews are no longer prohibited. However, the weddings of such couples must be officiated by Christian preachers, and all children produced by such marriages shall be baptized, and brought up only in the Christian religion.”
