Vigdís Finnbogadóttir (born 1930) was the President of Iceland (1980-1996) — the world's first directly elected female head of state, and Iceland's longest-serving president. A divorced single mother elected by a landslide.
Used widely in modern Iceland and Norway.
Vigdis is a compound name. Its parts are dís — each an attested element with a recorded meaning of its own.
Vigdis 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 Vigdis reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
