Ximena is the medieval Spanish form of Simone — from the Hebrew Shim'ōn (he has heard, listener) — via the Basque tradition. A top-200 US baby name (girls) since 2008. Doña Jimena Díaz (Ximena) (c. Princess Ximena of Asturias — Spanish royal heritage.
Ximena 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 Ximena reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
