Hi Suzette, The name Metzinger in German means 'butcher'. This name orginated from the name Metzger, and may have first been used in the town of Metz, Lorraine, France, which once was German territory. The traditional story, however, of the Metzinger, Motsinger, Matsinger, Mottsanger name of Swiss-German origin is that three Metzger brothers who lived in Lorraine were left a great deal of land and money by a relative. One of the brothers manipulated the other two out of their share, and disappeared into Holland or Switzerland, where he changed his name to Meizinger. About 1900 there reportedly was an unclaimed fortune left in Holland because no heirs could be found named 'Meizinger' and the money was used by the Holland government in their orphans fund.
I hope this helps you, note: when Hans Jacob arrived in America, he recorded his last name as Matzinger.
I have alot of information on the Motsinger family, let me know if I can help you further.
