What is the official language of the place where Regensberg was a family of counts from?
Regensberg family Regensberg was a family of counts from the Canton of Zürich in Switzerland. The family had possessions in the medieval Zürichgau from the probably mid-11th century and became extinct in 1331 AD. With the extinction of the male line, the city republic of Zürich laid claim to the Regensberg lands and formed the "Herrschaft Regensberg" respectively "Äussere Vogtei".
House of Amsberg The House of Amsberg (German: "von Amsberg" , Dutch: "van Amsberg" ) is the name of a German noble family from Mecklenburg. A great-grandson of a blacksmith, parish pastor August Amsberg (1747–1820) started calling himself "von Amsberg" in 1795 and the family's right to use this name was confirmed by the Grand Duke of Mecklenburg-Schwerin in 1891. By this permission to use a noble privilege, the family effectively became part of the untitled lower nobility of the Grand Duchy of Mecklenburg-Schwerin. The present King of the Netherlands, Willem-Alexander is an agnatic member of this family.
