If you don't mind a little swapping from one branch to another. The Anglo-Saxon Chronicles says, for 604 AD:

A.D. 604. This year Augustine consecrated two bishops, Mellitus and Justus. Mellitus he sent to preach baptism to the East-Saxons. Their king was called Seabert, the son of Ricola, Ethelbert's sister, whom Ethelbert placed there as king.
Ethelbert also gave Mellitus the bishopric of London; and to Justus he gave the bishopric of Rochester, which is twenty-four miles from Canterbury
