Gunnhild combines the Old Norse gunnr (battle) and hildr (battle) — "battle-battle." Gunnhild Konungamóðir ("Mother of Kings," c. 910-c. 980) was the wife of Eric Bloodaxe and mother of several Norwegian kings — one of the most powerful and controversial women of the Norse sagas, often portrayed as a sorceress.
Featured in Heimskringla and Egil's Saga.
Gunnhild is a compound name. Its parts are gunnr + hild — each an attested element with a recorded meaning of its own.
Gunnhild 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 Gunnhild reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
