Freya, the name of the Norse goddess of love, beauty and fertility, has long been popular in the U.K. but just beginning to be appreciated here. Freya could make a possible namesake for an ancestral Frieda. There is a Joseph Conrad novel titled Freya of the Seven Isles.
Currently Freya is immensely popular in several English-speaking countries: it's Number 16 in Scotland, 19 in England and Wales, 53 in Northern Ireland and 61 in Ireland.
A noted bearer was the explorer and writer Freya Stark.
