Etymology
Flaherty comes from the Irish Gaelic family name O'Flaitheartaigh, meaning 'descendant of Flaithbheartach.' The older explanations in surname books connect the name with flaith, meaning 'lord' or 'chief,' and with a second element interpreted as 'noble deeds' or 'chieftain-like.' In plain English, it was understood as a name for a noble or high-spirited ancestor.
History

Historical surname collections note several anglicized spellings, including O'Flaherty, Flaherty, Flagherty, Flaverty, Lafferty, and Laverty. The surname spread widely through Irish diaspora communities, and it remains common in the United States and Ireland.
