This is the profile Thorri,
King Thorri Snærsson, of Kvenland
Thorri had two sons Gór and Nór and a daughter Goi. So I can see only Gor and Goi. Why is Nór removed from the father Thórr ?
This is the profile Nór/ri.
Nor Thorrasson, legendary king In Alfheim
Would someone remove the wrong parent Halvdan and set Nor correct father.
There is no documentary that Halvdan is the father.
This old Scandinavian profile would not possible have any reliable documents,
so we are tighted up for oral tradition and later on written saga documents as Is the case with Biblical persons.
