Ó Maolmhuaidh

Maolmhuaidh is an Irish surname, generally anglicised as Molloy or Mulloy. Like other Irish surnames, Maolmhuaidh is patronymic. The male version is Ó Maolmhuaidh with the name in the genitive or possessive case preceded by ("ó" or “ua” meaning "grandson or descendant"); the female versions is Ní Mhaolmhuaidh ("ní" a contaction of “iníon” meaning "daughter”, there is no equivalent of Mrs as women in gaelic society retained their maiden names after marriage); the family or house name is Uí Mhaolmhuaidh “uí” being plural of “ua” or “ó”.

Ó Maolmhuaidh Fir Cell
The Uí Maolmhuaidh of Fir Cell (men of the churches, in what is now County Offaly) claimed descent from the southern Uí Néill. The 16th-century mercenary, Captain Greene O'Mulloy, was of this family.
