Esma is from the Arabic Asmā' (أسماء — names) — also used as feminine across Bosnian, Romani, Turkish, and Albanian communities. Roma cultural icon.
Esma 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 Esma reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
