Conrad I, Count of Auxerre
Conrad I the Elder (died about 864) was the count of several counties, most notably the Aargau and Auxerre, around Lake Constance, as well as Paris from 859 to 862/4. He was also the lay abbot of Saint-Germaine in Auxerre. Conrad's father was Welf. He was one of the early Welfs, a member of the Bavarian branch, and his sister Judith was the second wife of Louis the Pious.
In 858, he and his family, abandoned their sovereign Louis the German and went over to Charles the Bald, Judith's son. They were generously rewarded and Conrad was appointed to many countships. Louis the German confiscated his Bavarian fiefs and lands.
