The legend, contained in a Latin Passio, tells that Eormenred and his wife Oslafa had several children including the two sons Aethelred and Aethelberht, and a daughter Eormenbeorg, also known as Domne Eafe.
(It is likely that such a residence existed, for Sir Frank Stenton pointed out that the placename Eastry, comparable to Surrey in formation, represented an early administrative centre.)
At about this time Egberht's mother Queen Seaxburh founded her own double monastery at Minster in Sheppey, on the south bank of the Thames Estuary nearly opposite Wakering.
In addition to the Latin Passio (edited by David Rollason) a version of the story appears in Roger of Wendover's Flores Historiarum (Flowers of History), compiled in the early thirteenth century.
Excavations at Great Wakering have recently uncovered a site of Middle Saxon occupation including a fragment of ornamented stone-sculpture, which may derive from the place named in the legend.
