Celia is from the Latin caelum (heaven, sky) or alternately a feminine of the Roman Caelius. Celia Cruz (1925-2003) — born Úrsula Hilaria Celia de la Caridad Cruz Alfonso de la Santísima Trinidad — the Cuban-American singer crowned "the Queen of Salsa" and the most influential Afro-Latina musician of the 20th century. 23 gold albums, 3 Grammy Awards, 4 Latin Grammys, and her signature shout "¡Azúcar!" became a Spanish-language cultural rallying cry. Fled Cuba in 1960; refused to return after Fidel Castro denied her entry to her mother's funeral in 1962. First Latina featured on a US quarter (2024). *Celia (in Shakespeare's As You Like It) — Rosalind's loyal cousin*.
Subject of Celia (2015 Telemundo telenovela) and the US Mint's American Women Quarters Program.
In Pythagorean numerology the letters of Celia reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
