Cassey

Meaning & origin

Cassey is a feminine spelling variant of Casey, an Irish surname turned given name. It first appeared in U.S. birth records in 1968, during a period when Irish names were gaining popularity. The name reached its peak rank in 1986, reflecting the broader trend of Casey and its variants being fashionable for girls in the 1980s. Since 1987, however, the name has been steadily declining in use. Cassey shares its roots with the more common Casey, which remains a unisex choice, though Cassey is overwhelmingly given to girls. The name lacks a strong association with any particular state, as it has never ranked in the top 1000 nationally. Despite its decline, Cassey retains a familiar sound and a connection to Irish heritage.

Cassey is a modern spelling variant of Casey, which originates from the Irish surname Ó Cathasaigh, meaning 'descendant of Cathasach'. The personal name Cathasach derives from the Gaelic word 'cathasach' meaning 'vigilant' or 'watchful'. The surname was anglicized as Casey, and by the 20th century, it became used as a given name for both boys and girls. The spelling Cassey emerged as a feminine variant, particularly in the United States, where it peaked in popularity for girls in 1986.
