Moran surname meaning

Moran is often an Irish patronymic from Ó Móráin, “descendant of Mórán.” The personal name Mórán is traditionally connected with mór, “great” or “large.” Irish surname references also record Ó Mughróin, a separate patronymic associated with the personal name Mughrón, so a single gloss cannot cover every Moran family. Morán, O’Moran, and Morin may reflect accent, language, or regional spelling histories rather than one direct line. Parent’s name is the closest catalog type because the principal Irish routes are patronymic, but confidence is disputed because the competing origins are well documented.
