 He had livery of his lands on 18 July 1222.
Edmund Butler, Earl of Carrick and 6th Chief Butler of Ireland (1268 – 13 September 1321) was a noble in the Peerage of Ireland.
 He was the second son of Theobald Butler, 4th Chief Butler of Ireland.
 Edmund went on pilgrimage to Santiago de Compostela in 1321 but died in London on 13 September 1321.

Thomas Butler, 1st Baron Dunboyne (1271-October 9 1329) was the third son of Theobald Butler, 4th Chief Butler of Ireland and Joan FitzJohn.
Theobald Butler, 3rd Chief Butler of Ireland (1224 – December 26 1248) was 6 years old when his father, Theobald died.
 His mother was Joan de Marisco, daughter of the Justiciar of Ireland, Geoffrey de Marisco.
Baron Dunboyne was a title first held by the Petit family some time after the Norman invasion of Ireland.
 Dunboyne was part of the Lordship of Meath.
 The Petit family also had land holdings in Mullingar.
 In 1227, Ralph Petit became Bishop of Meath.
 In that capacity he founded a priory of the Blessed Virgin in Mullingar and he endowed this establishment with the townland of Kilbraynan (or Kilbrena) in Dunboyne, along with the rectory of Dunboyne, its tithes and other ecclesiastical revenues.
 A century later, Thomas Butler, son of Theobald Butler, 4th Chief Butler of Ireland, married Sinolda, heiress of William le Petit.
 In 1324, Butler was created Baron Dunboyne by prescription.
 In this way, the Dunboyne properties and titles passed to the Butlers.
 In 1541, the barony was created by patent in the Peerage of Ireland.
 The barons are alternately numbered from the early 14th century by numbers ten greater than the number dating to the patent (e.g. the 28th/18th Baron Dunboyne died May 19, 2004).
 The first baron of this sequence in turn married the heiress to an earlier line of Barons Dunboyne.

 It was, however, revived on May 6, 1583 in Theobald's favour.
 He became the 1st Baron Cahir (of the second creation) and ruled much of the barony of Iffa and Offa West.
