Oneall Origin and Meaning

The name Oneall is a boy's name.

Oneall is a masculine name that appears to be a variant spelling of O'Neill, a prominent Irish surname meaning 'descendant of Niall.' The traditional O'Neill clan is one of Ireland's most important historical families, tracing their lineage to Niall of the Nine Hostages, a High King of Ireland in the 5th century. As a first name, Oneall represents a modern adaptation of this prestigious surname, transforming a family heritage into a personal identity. The simplified spelling removes the apostrophe while maintaining the phonetic sound of the original. Though quite rare as a given name, Oneall carries rich historical associations with Irish nobility, strength, and leadership. It offers a connection to Celtic heritage in a unique naming choice.
