He was the third son of Côme Clausse and Marie, the sister of bishop Jérôme Burgensis. In 1571, Burgensis resigned from bishopric; Marchaumont succeeded him. He was consecrated by Cardinal Charles of Lorraine.
Marchaumont died on 12 September 1573, at the age of 28 after a one-year, one-month and fifteen-days-long bishopric.[1] Then the title was given to his younger brother Côme Clausse de Marchaumont.[2]
