the thing about maiden/matron (whose usage I personally like here) is that it relates to norns.
These three Norns are described as powerful maiden giantesses (Jotuns) whose arrival from Jötunheimr ended the golden age of the gods.

The Germanic Matres and Matrones, female deities venerated in North-West Europe from the 1st to the 5th century AD depicted on votive objects and altars almost entirely in groups of three from the first to the fifth century AD have been proposed as connected with the later Germanic dísir, valkyries, and norns,[43] potentially stemming from them.
