Erzsébet is the Hungarian form of Elizabeth. Saint Erzsébet of Hungary (1207-1231) was the Hungarian princess who, widowed at twenty, gave away her wealth to the poor and joined the Third Order of Saint Francis — patron saint of the Third Order Franciscans and a national symbol of Hungary. Canonized just four years after her death.
Featured in Liszt's oratorio The Legend of Saint Elizabeth.
Erzsébet 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 Erzsébet reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
