The House of Hohenzollern is a noble family and royal dynasty of electors, kings, and emperors of Prussia, Germany, and Romania. It originated in the area around the town of Hechingen in Swabia during the 11th century. They took their name from their ancestral home, the Burg Hohenzollern castle near Hechingen.
Duchess Louise of Mecklenburg-Strelitz (Luise Auguste Wilhelmine Amalie; 10 March 1776 – 19 July 1810) was Queen consort of Prussia as the wife of King Frederick William III. The couple's happy, though short-lived, marriage produced nine children, including the future monarchs Frederick William IV of Prussia and German Emperor Wilhelm I.
