Conrad I, Count of Auxerre

Conrad the Elder was a prominent noble in the Carolingian Empire, and member of the Elder House of Welf. He was count of several counties in Alamannia, most notably the counties of Argengau and Linzgau, north of the Lake Constance. Conrad was son of count Welf I and countess Heilwig. Both of Conrad's sisters married into the Carolingian dynasty: the elder Judith was second wife of emperor Louis the Pious, while younger Emma was wife of king Louis the German of East Francia.
