Molloy

Molloy is an Irish surname, anglicized from the Gaelic Ó Maolmhuaidh or Ó Maol Aodha. The name derives from two distinct septs, each with its own origin and history.

The primary sept, Ó Maolmhuaidh, belonged to the southern Uí Néill, a powerful tribal group claiming descent from Niall of the Nine Hostages, the legendary fifth-century king who is said to have kidnapped Saint Patrick to Ireland. The name means "descendant of Maolmhuadh"—maol meaning "chief" or "bald" (a reference to the distinctive tonsure of early Irish monks) and muadh meaning "proud" or "noble." Thus, the name may be interpreted as "proud chief." This sept held territory in what is now County Offaly, where the surname remains common today.

The second sept, Ó Maol Aodha, translates as "descendant of the devotee of (Saint) Aodh," from maol ("bald" or "tonsured one"). This family originated in east Connacht, in the region spanning County Roscommon and the east of County Galway, and is still numerous there. Over time, the surname has given rise to several variants including Malloye, Mulloy, Maloy, Miley, and Millea.

Notable bearers of the surname include Aaron Molloy (born 1997), an Irish footballer, and many others from various fields. The name Molloy appears in literature as the title character of Samuel Beckett's renowned novel Molloy.
