Ingjald "Hviti" Olavfsson seems to have been merged with Gudrød Rognvaldsson. A remaining profile of Gudrød is here: http://www.geni.com/people/Gudr%C3%B8d-of-Agder/6000000008177239500
Someone needs to sort out this with reference to sources, but I don' t have them handy (just idle-merging while listening to a meeting).
Please add notes to this discussion if possible!
