Nuala is from the Irish Nuala — shortened form of Fionnuala from Irish fionn (white/fair) + guala (shoulder) — fair shoulder. Nuala is one of the Irish feminine names — central to traditional Irish mythological heritage. 1996 bestseller. Irish feminine name reflecting Celtic mythological heritage.
Nuala 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 Nuala reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
