Flannery comes from an Irish surname, the anglicized form of Ó Flannghaile meaning “descendant of Flannghal”, Flannghal meaning “red valor”, “red fury”, or “red ardor” made up from Irish flann (red, blood-red) derived from PIE root word *welh₃- (to hit, to strike); and gal (warlike ardor; valor, fury) from Proto-Celtic *galā (might, ability). Flannery could also be the anglicized form of Flannabhra meaning “red eyebrows” from Irish fabhra (eyelash; eyebrow).
