Xiomara is the Spanish form of an Old Germanic compound — guma ("man, warrior") + mara ("famous, renowned") — "famous warrior." A top-500 US baby name since 2012 in Hispanic communities. Xiomara Acevedo — Honduran feminist activist. Xiomara González — Puerto Rican Olympic boxer.
Xiomara 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 Xiomara reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
