Magnus Haroldsson

Son of Harold and his mistress, probably Eadgyth Swanneshals (Edith the Fair, aka Edith Swanneck).

Children of Harold:

1. Godwin

2. Edmund

3. Magnus

4.Gytha (legitimate)

5. (Ulf?)

6. Gunhild

from Medieval Lands:

4. MAGNUS ([1050/55]-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[2067]. He may also have taken part in their raids in south-west England. At least one of these raids/attempted reconquests involved a force of Danes, English exiles, Poles, and Frisians.

Medieval members of the Zaremba Clan in Poland claimed descent from the Magnus who served as comes (wojewode or provincial governor) first of Silesia (c. 1093) and later of Masovia (c. 1109). Recently, some genealogists and historians have proposed that Magnus Haroldsson is the same person as this Magnus. This Magnus apparently also represented the king of Poland at the marriage of Harald's daughter Gytha and the prince of Kiev. (See the 3/25/00 note by Rafal T.
