McNulty
McNulty (MacNulty) is an Irish surname historically associated with County Donegal in northwest Ireland and, possibly, with the moniker Ultach, an agnomen (additional surname) used by some of Gaelic Ireland's MacDunleavy or MacDonlevy (dynasty) royals in its earlier Gaelic language form. The surname denotes that its bearer is of the ancient Irish Ulaid race (singl. Ultaigh). In alternate spelling, Ulaid may be encountered as Ulaidh or Uladh. It is pronounced in Gaelic language "Ully" and has been corrupted in English to "ulty".
