Padraig Mac Giolla-Domhnaigh

Goodman—In the districts surrounding Castleblaney, Co. Monaghan, the McGuigans have, in many cases, assumed the name of Goodman, and in the districts of Carrickmacross, in the same county, they have assumed the names of Pidgeon and Fidgeon. McGuigan takes the form of M'Quiggan and M'Wiggan in Galloway, and Wiggin in the Isle of Man. Father Woulfe gives Mac Giollamhaith as the Gaelic of this anglicised name. Mag Uiginn is the correct form of M'Guigan.
