About Spanish names

Spanish names blend Latin bones with centuries of devotion — many of the most beloved, like Dolores, Guadalupe, and Consuelo, began as titles of the Virgin Mary. Vowel-rich endings give them warmth and music, and family custom often honors grandparents or saints. From Mateo to Lucia, they tend to sound expressive and openhearted, and they thrive on both sides of the Atlantic.

Meaning and origin are editorial; U.S. popularity comes from Social Security Administration public files.
