Ireland: In modern times, Phillips, an English name, has to some extent taken the place of Philbin, the Irish diminutive of Philip. With the prefix ‘Mac’, it is found in Cavan and Monaghan and there it is usually a branch of the Scottish clan MacDonnell of Keppoch. MacPhilbin is the name of one of the hibernicized branches of the Connacht Burkes which formed a sept of the Irish type. O’Donovan says there were two branches, one in Mayo and one in Co. Galway. Of those Danish families that immigrated to Ireland, some took Irish surnames and more of them added the prefix ‘Mac’ to their names, as did many of the Anglo-Norman and English families in earlier times. Some branches of the De Burgo (Burke, de Burgh) family of Connaught took the surname MacWilliam and some of them that of MacPhilip. The De Burgo (Burke, de Burgh) name is one of the most important and most numerous of Hiberno-Norman names. First identified in Connaught, it is now numerous in all the provinces (least in Ulster).
