Gefjon (Gefjun) is the Old Norse goddess whose name means "giver." According to Snorri, she plowed the island of Zealand out of Sweden by transforming her four sons into oxen — the iconic Gefion Fountain in Copenhagen (1908) commemorates the legend.
Goddess of plowing, fertility, virginity.
Gefjon does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Gefjon reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
