I think it is beyond fantasy to suggest that this woman,"Fruen til", was married to two viking kings of Dublin both named Ivar.
Therefore the question is raised, are we (as Geni members) merging Ivar Beinlauss "Ivar the Boneless" with Imar ua Ímair Ivarr Gudrodson, king of Dublin?
I don't know of any sources for Ivar Beinlauss having children, so if we do not merge the children currently attached to him need to be disconnected and moved over to Imar.
Note: I am calling them Ivar and Imar for simplicity, obviously both men are known by various spellings of the same name.
