Career
Both Gebhard and his older brother were founding members of the Schmalkaldic League. A dispute between Gebhard and his brother, Johann Albert, Graf von Mansfeld zu Arnstein (1522–1586) in 1546, led to mediation by Martin Luther. In 1558, Gebhard of Mansfeld was elected archbishop of Cologne. During his tenure, the Diocese of Utrecht ceased to be a suffragan of Cologne, and the Deanery of Zyfflich was incorporated with the newly foundedFamily
As ''Domherr,'' a member of the Cathedral chapter, he lived in concubinage. He had at least one surviving child, a daughter Sybilla, who married, first, Eduard (Egbert) von Bocholtz (died after 1590); and second, Johann Eggenoy (died before 1616).References
