Mac Aodhagáin Explained

Mac Aodhagáin (English: Egan or Keegan), is an Irish Gaelic clan of Brehons who were hereditary lawyers - firstly to the Ó Conchobhair Kings of Connacht, and later to the Burkes of Clanricarde.[1] [2]

The earliest surviving Irish law manuscript, In Senchas Már, was written prior to 1350 at a school (patronised by the Mac Aodhagáin) at Duniry, near Loughrea.[1] Other branches of the clann maintained schools at Park, outside Tuam, and at Ballymacegan in Co. Tipperary.[3]
