Yangzom is from the Tibetan ཡང་འཛོམས་ (Yang-'dzoms — melody collector, holder of harmony). Yangzom is one of the Tibetan + Bhutanese feminine names — central to traditional Vajrayana Buddhist heritage.
Yangzom 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 Yangzom reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
