About Edmund Haroldsson
Son of Harold and his mistress, probably Eadgyth Swanneshals:
from Medieval Lands:
3. EDMUND ([1047/55]-after 1069). Florence of Worcester records that "Haroldi regis filii Godwinus, Eadmundus, Magnus" returned from Ireland and landed in Somerset where they were defeated, in a passage which deals with events in mid-1068. The Anglo-Saxon Chronicle records that "the sons of King Harold" (unnamed, and without specifying how many sons there were) came from Ireland and landed in "the mouth of the Taw", where they were defeated by "Earl Brian", before returning to Ireland. Florence of Worcester records that "duo Haroldi filiis" sailed from Ireland 24 Jun  and landed "in Ostio flumis Tavi".
