Meaning & origin
Casilda is a rare Spanish name with a long but quiet history in the United States. First recorded in 1915, it saw a slight uptick in the 1930s, reaching its peak year in 1934, but never entered the top 1000. The name is almost entirely absent from recent records, reflecting a stable but ultra-low trajectory. Its association with Saint Casilda, a 10th-century Spanish saint, gives it a distinct religious and cultural resonance. While the name has not been given to enough children to calculate a 1-in-N statistic, its enduring if minimal use suggests it appeals to families seeking a unique and historically rooted name. No top states have registered notable usage, indicating its rarity across the country.
Casilda is a name of uncertain origin, possibly derived from a Visigothic element meaning 'battle' or 'strength.' It is associated with Saint Casilda, a 10th-century Spanish saint who converted to Christianity and is venerated in Toledo. The name has been used primarily in Spanish-speaking regions, though it remains rare.
