Meaning & origin

Dacey is a rare given name that has never broken into the top 1000 U.S. rankings. First recorded in 1974, it saw its peak usage in 2002 but has been declining since 2001. Despite its obscurity, Dacey offers a melodic, unisex appeal similar to names like Macy and Casey. Its origins are unsettled, with possible Irish or French roots, adding an air of mystery. Parents drawn to uncommon but accessible names may find Dacey an intriguing choice.

Dacey is a name of debated origin. It may derive from the Irish surname Ó Déasaigh, meaning 'descendant of Déasach', or from the French surname Dacey, itself a variant of Dassy. The name has seen occasional use in English-speaking countries, particularly in the United States since the late 20th century.
