Uxía is the Galician form of Eugenia — from the Greek eu-genes (well-born). A beloved Galician feminine name. Uxía Senlle (born 1962) is the Galician folk singer.
Used widely in modern Galicia (northwestern Spain).
Uxía 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 Uxía reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
