Andrew Kauders is born Swiss.
Kauders are Bohemian jews:
The KAUDERS family was one of the earliest Jewish families in Körmend, as well as one of the wealthiest.
The earliest KAUDERS family member in the town was probably Veit KAUDERS, born around 1740, probably in Bohemia, who came to Körmend around 1760 and died there around 1810. The names Veit (and variants Feit and Vitus) and KAUDERS were much more common in Bohemia than in Hungary, with the KAUDERS name occurring in Prague since at least the 17th century. In the 18th century, many young Jewish men moved from Bohemia and Moravia to Hungary. According to a law issued in 1726 by Charles III and designed to limit the growth of the Jewish population in those provinces of the Monarchy, only the first-born Jewish son was allowed to marry locally. Bohemian Jews were mostly German-speaking and they tried to move to areas where Jews were similarly German-speaking. This may have been the reason Veit KAUDERS moved to Körmend.
