Son of a certain Sigebald, succeeded c.650. Bede described him as a friend of Oswiu, king of Bernicia, who, after the conversion of Peada of Mercia, persuaded Sigeberht to follow his example. He was baptized by bishop Finan in the kingdom of Northumbria, near Hexham, and bishop Cedd was despatched to Essex to effect the reconversion. Bede recorded that the king was murdered c.660 by two of his immediate court in what sounds like a dispute about pagan marriage practices. The church at Bradwell-on-Sea in Essex, built in Sigeberht's time, survives. His conversion earned him the epithets ‘the Good’ and ‘Sanctus’.
