Mac Aodhagáin
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. 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.
