"Megonnigil" A variant spelling of MacGonigal. Irish (Donegal) and Scottish (Glasgow): Anglicized form of Gaelic Mag Congail, a patronymic from the personal name Conghal, composed of Celtic elements meaning ‘hound’ + ‘valor' derived from the Irish Clan Mac Congail. The principal thing to be noted is their constant association with Co. Donegal. Apart from the adjacent parts of Co. Derry they were very seldom to be found elsewhere. Some of the sept were counted among the warlike followers of O'Donnell; but they were primarily an erenagh family. It is as ecclesiastics they are best known in history. The Annals of Ireland by the Four Masters shows "Mac Gonigal" as early as 1238AD.
