Misc. Notes
Richard Og de Burgh (1259 –1326, Athassil monastary), also known as Richard de Burgh, was the 2nd Earl of Ulster, 3rd Lord of Connacht. His name, "Richard Og" meant Richard the Young, probably a reference to his youth when he became earl in 1271, or to differentiate him from his grandfather, Richard Mor. He was also known as the Red Earl.
Richard Og was the most powerful of the de Burgh Earls of Ulster. He was a friend of King Edward I of England, and ranked first among the Earls of Ireland. Richard's wife Marguerite de Guines was the cousin of King Edward's queen. He pursued expansionist policies that often left him at odds with fellow Anglo-Irish lords; he successfully defeated the King Felim mac Aedh Ua Conchobair of Connacht at the Second Battle of Athenry in 1316.
His sister, Egidia de Burgh, was wife of James the Stewart of Scotland. His second son, John de Burgh, was husband to Elizabeth de Clare, a granddaughter of Edward I of England. Of his daughters, Catherine married the Maurice Fitzgerald, 1st Earl of Desmond; Joan married the Maurice FitzThomas FitzGerald, 4th Earl of Kildare; Avelina married John Earl of Louth; Matilda married Gilbert de Clare, 8th Earl of Gloucester; and Elizabeth de Burgh married Robert the Bruce, later Robert I of Scotland. His son John died in 1313, leaving the succession to his infant son, William.
