Earl of Ormond (Ireland) in the context of "Kilcooly Abbey"

Butler (Irish: de Buitléir) is the name of a Hiberno-Norman noble family whose members were, for several centuries, prominent in the administration of the Lordship of Ireland and the Kingdom of Ireland. They rose to their highest prominence as Dukes of Ormonde. The family has produced multiple titles such as Baron Cahir, Baron Dunboyne, Viscount Ikerrin, Viscount Galmoye, Viscount Mountgarret, Viscount Thurles, Earl of Carrick, Earl of Kilkenny, Earl of Ormond, Earl of Ossory, Marquess of Ormonde and Duke of Ormonde. Variant spellings of the name include le Boteler and le Botiller. The Butlers were descendants of Anglo-Norman lords who participated in the Norman invasion of Ireland in the 12th century. The surname has its origins in the hereditary office of "Butler (cup-bearer) of Ireland", originating with Theobald Walter, 1st Chief Butler of Ireland. The arms of later family members depicted three cups in recognition of their original office.

Thomas Boleyn, 1st Earl of Wiltshire, 1st Earl of Ormond, 1st Viscount Rochford KG, KB (c. 1477 – 12 March 1539), of Hever Castle in Kent, was an English diplomat and politician. He was the father of Anne Boleyn, the second wife of King Henry VIII, and was thus the maternal grandfather of Queen Elizabeth I. By Henry VIII, he was made a Knight of the Garter in 1523 and was elevated to the peerage as Viscount Rochford in 1525, and in 1529, he was further ennobled as Earl of Wiltshire and Earl of Ormond.

James Butler, 9th Earl of Ormond and 2nd Earl of Ossory (c. 1496 – 1546), known as the Lame (Irish: Bacach), was in 1541 confirmed as Earl of Ormond thereby ending the dispute over the Ormond earldom between his father, Piers Butler, 8th Earl of Ormond, and Thomas Boleyn, 1st Earl of Wiltshire. Butler died from poison in London.

Earl of Desmond (Irish: Iarla Dheasumhan meaning Earl of South Munster) is a title of nobility created by the English monarch in the peerage of Ireland. The title has been created four times. It was first awarded in 1329 to Maurice FitzGerald, 4th Baron Desmond, a Hiberno-Norman lord in Southwest Ireland, and it was held by his descendants until 1583 when they rose against the English crown in the Desmond Rebellions. Following two short-lived recreations of the title in the early 1600s, the title has been held since 1628 by the Feilding family of Warwickshire, England. The current holder is Alexander Feilding, 12th Earl of Denbigh and 11th Earl of Desmond (4th creation). The Earldom historically comprised what is now the entirety of County Limerick with large swathes of County Cork, County Kerry and County Waterford also being included. It bordered the Kingdom of Desmond, Kingdom of Thomond and the Earldom of Ormond
