I'm sorry to say, but unless you're interested in a good fairytale for your children, you shouldn't look for a relationship to sagafigures. Your link back to Angantyr is most certainly not provable by good reliable sources.
I checked my own link back to her and it should be broken around the years 1200-1300 the reason being the lack of trustworthy sources and that is 800 years after Angantyr lived.
Please, all users of Geni, try to make our ancestry trustworthy. It is the responsibility of all of us, to try to make our family relations as trustworthy as possible according to the most trustworthy sources we can find.
