Burchard was an Anglo-Saxon Benedictine monk possibly of noble birth, and educated at Malmesbury Abbey.

[2] He left England after the death of his parents and joined Boniface (who may have been a relative) in his missionary labors, some time after 732.

As was customary at the time, his appointment was approved by Carloman (mayor of the palace), who endowed the diocese with a number of benefits.

In 750, with Fulrad of Saint-Denis, he brought to Zachary the famous question of Pepin, whose answer was supposed to justify the assumption of regal power by the Carolingians.

[4] In 751, he resigned his see in favor of Megingoz, a Benedictine monk from St. Peter's Abbey in Fritzlar,[5] and retired to a life of solitude.
