An uncommon Irish pick — distinctive and rare.
Dempsy is a boy's baby name of Irish origin, a variant of Dempsey, from the Gaelic Ó Díomasaigh meaning 'descendant of the proud one.' The name gained fame through boxing legend Jack Dempsey, world heavyweight champion from 1919 to 1926.
With its punchy, one-two syllable rhythm, Dempsy has a rugged, spirited character that feels both distinctly Irish and timelessly American.
Dempsy has 15+ years of history in the U.S., first appearing in 1916.
