He was the commander of the Anglo-Irish army in the Battle of Faughart, the decisive battle in the Irish Bruce Wars 1315–1318. In this battle, Edward Bruce was killed, and Bermingham had Bruce's severed head 'salted in a chest' and transported to England to be put on display before Edward II. He was briefly Viceroy of Ireland in 1321.[1] Bermingham was the son of Piers FitzJames MacPhioris de Bermingham and Ela de Odingsells. He was contracted to marry Matilda de Burgh in 1308 but was married to Aveline de Burgh: both were daughters of Richard Óg de Burgh, 2nd Earl of Ulster. … He had three children with Aveline: their son Richard, Lord Ardee, died in 1322. Their daughter Catherine married Edmund Lacy and the other daughter, Maud de Bermingham, married Sir William Tealing.[2]. … Bermingham was killed in the Braganstown massacre on 13 June 1329 in a feud between the Anglo-Irish families of Louth, along with some 200 members of his family and household.
