The Huosi were one of the Uradel noble families in the stem duchy of Bavaria, during the reign of the Agilolfing dynasty. They were mentioned in the 743 Lex Baiuvariorum. Their original homeland was the town of Pfaffenwinkel in Oberbayern.
Many abbeys in southern Bavaria such as Benediktbeuern, Ilmmünster, Scharnitz, Schlehdorf and Tegernsee were founded in the 8th century by people who were reportedly members of the Huosi.
History
The origins of the Huosi are unclear. The dynasty appears to have started as petty Germanic chieftains under the Goths. Sometime around the Christianization of Germany, the Huosi were converted to Chalcedonian Christianity from Germanic paganism, although it is probable that some were already Arians.
Several descendants held the office of a Bishop of Freising in the 9th century. They may have affiliated with the later Luitpolding dynasty. One of them was Arbeo of Freising (723 or earlier near Meran – 4 May 784), an early medieval author and Bishop of Freising from 764.
