Baron Dunboyne


Baron Dunboyne was a title first held by the Petit family some time after the Norman invasion of Ireland.

History

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 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.

The first baron of this sequence in turn married the heiress to an earlier line of Barons Dunboyne.
The family seat is Argo Hill House, near Rotherfield, East Sussex.
