In "Charcoal Nils and the Troll-Woman" (Hofberg, p. 148. From
Vestmanland) we have the story of a strange union. Malicious as
the troll-folk are, when a marriage takes place between a
troll-woman and a human being, the woman is beyond reproach,
good and kind, the only reproach that can be made her is that
she is not a Christian.
