Richard de Burgh, 2nd earl of Ulster - known as the Red Earl of Ulster

Born -  Unknown but around 1259    Died - July 29, 1326 at Athassel Monastery, near Cashel, County Tipperary.

One of the most powerful Irish nobles of the late 13th and early 14th centuries, a member of a historic Anglo-Irish family the Burghs and son of Walter de Burgh (c. 1230-71), the 1st Earl of Ulster (of the second creation).

In 1286 he led a ferocious attack on Connaught and reestablished his family's power base , deposing Brian O'Neill as the chief native king and substituting a nominee of his own. He led his forces from Ireland to support England's King Edward I in his Scottish campaigns and when the forces of  Edward de Bruce's invaded Ulster in 1315, the Earl led a force against him, although he had given his daughter Elizabeth in marriage to Robert de Bruce who later became King of Scotland in around 1304. 

Cousins of Richard de Burgh were the De Mandeville's who ruled the Route from their seat at Dunluce Castle, they are believed to have been descendent from William de Mandeville, the Earl of Essex. Their is also a link between the De Mandeville's, Dunluce Castle and the McQuillen's clan.  The chief of the McQuillen's was also a Lord of the  Route and  believed to have lived at Dunluce Castle - One theory suggest the MacQuillen's came from the De Mandeville's line and gaelicized their name to MacUighilin  or MacHugelin and that MacQuillen is a derivative of that.  It was common for Anglo Norman's who settled in Ireland to gaelicize  their names - many became, as an old saying goes ' more Irish than the Irish' - a fact that seems to go hand in hand with many Anglo-Irish people.
