History & Origin

Una derives from the Latin una, the feminine form of unus, meaning 'one.' It is also the Anglicization of the Irish Gaelic name Úna, used in Ireland since at least the early medieval period. The Irish etymology is uncertain — possible connections to uan (lamb) or older Gaelic roots have been proposed. Edmund Spenser immortalized the Latin-inspired form in his 1590 allegorical epic The Faerie Queene.

Una has been used in Ireland, Scotland, and England for centuries. The Irish form Úna was borne by several legendary and historical figures. In the 20th century, Una gained modest use in the English-speaking world as a short, elegant alternative to longer -una names. It has been experiencing a quiet revival as parents seek spare, classical two-syllable names.

Did you know? Edmund Spenser named the heroine of The Faerie Queene (1590) Una to represent the One True Church and the virtue of Truth — giving this simple two-syllable name enormous allegorical weight.
