[7] þriðjung ‘a third’: See Note to GizGrý Lv 1/5 (Heiðr 99) on the inheritance of the hornungr ‘bastard’, as Hlǫðr is called there. The closest parallel to the situation described here appears to be in Langobardic law, which allowed an illegitimate son to inherit one third where there was one legitimate son, who inherited two thirds (Grimm 1899, 655-6).
