Petermann von Raron (c. 1405–1479) was the last baron of Raron, and lord in Toggenburg, participating in the Old Zürich War on the side of the Confederacy. He inherited the rights to the Toggenburg in 1437 via his mother Margaretha of Rhäzuns. Petermann moved to the Toggenburg while his brother Hildebrand remained in the Valais, leading to a de facto division of the Raron lands, even though both brothers nominally were co-regents of the entirety patrimony. Petermann sold Uznach to Schwyz and Glarus in 1437/8. He fought on the side of the Confederacy in their invasion of the territory of Zürich in 1440/1. He later participated in the siege of Winterthur (1460) and in the Waldshut feud against Sigismund, Archduke of Austria (1468). Both Hildebrand and Petermann died without issue, and the family was extinct upon Petermann's death in 1479. References Edwin Hauser: Geschichte der Freiherren v. Raron. Zürich 1916.
