Delores is an American spelling variant of Dolores — from the Spanish María de los Dolores ("Mary of the Sorrows"), referring to the Seven Sorrows of the Virgin Mary in Catholic devotion. The name remains tied to its devotional Catholic roots while functioning as a vintage-Americana revival candidate alongside Doris and Gloria. Saint Mary of the Sorrows is venerated on September 15 (the Feast of Our Lady of Sorrows). Delores Wells — Playboy model and actress.
Delores 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 Delores reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
