Overview
The de Barry family was a medieval Cambro-Norman noble lineage whose principal historical territories lay in Pembrokeshire and south Wales, and later in parts of southern Ireland. It is not a commercial brand in the modern sense; the name identifies a hereditary aristocratic family and its associated estates, titles, castles, and political influence. The family name was also rendered in forms such as de Barri and Barri. The family’s traditional founder was Odo de Barry, a Norman knight who participated in the Norman conquest of England and the extension of Norman power into south-east Wales during the eleventh century. In return for military service, Odo received substantial lands in Pembrokeshire and around Barry in Glamorgan, including the island now known as Barry Island. The family name was linked to these Welsh possessions. Gerald of Wales, a prominent twelfth-century churchman and writer who was Odo’s grandson, explained the name’s origin by associating it with the island of Barri and the local saint Baroc. Odo’s son, William FitzOdo de Barry, became an important ancestor of the Irish branch. He established or strengthened the family’s position at Manorbier in Pembrokeshire, where the family held a large manor that included Jameston, Manorbier Newton, Begelly, and Penally. The original fortification at Manorbier was a motte-and-bailey castle; William is associated with its rebuilding in stone. The family retained the lordship of Manorbier until the fifteenth century. During the late twelfth century, members of the family became involved in the Norman intervention in Ireland. Robert de Barry accompanied his half-uncle Robert Fitz-Stephen and took part in the siege of Wexford before being killed at the battle of Lismore in 1185. Philip de Barry arrived in Ireland in the same year to assist Robert Fitz-Stephen and Raymond FitzGerald in recovering territories in what is now County Cork. These lands included the cantreds of Killede, Olethan, and Muscarydonegan. Olethan corresponded broadly with the former Uí Liatháin territory, while Muscarydonegan is associated with the area now represented by the barony of Orrery and Kilmore. The family’s Irish territorial position was formalized and expanded through royal grants and confirmations. In 1181, Robert de Barry was associated with the title Baron Barry of Olethan and Ibawne. In 1206, King John confirmed Philip’s son William de Barry in possession of the territories and granted him the lordships of Castlelyons, Buttevant, and Barry’s Court in eastern County Cork. The family subsequently became a major Anglo-Norman landholding house in Ireland. The de Barrys occupied several important offices and acquired higher titles over time. David de Barry was appointed chief justice of Ireland by Henry III in 1267, while another William de Barry served as justice in eyre from 1289 to 1294. John Barry was raised to the viscountcy of Buttevant in 1385, and David Barry was elevated to the earldom of Barrymore in 1627. Their history was intertwined with neighboring Irish dynasties, particularly the MacCarthy Reaghs and the MacCarthys of Muskerry. Intermarriage and cultural adaptation led some branches to become increasingly Gaelicized, and later genealogical traditions even attributed a Gaelic paternal origin to portions of the family. Barryscourt Castle near Carrigtwohill served as the family seat from the twelfth century until 1617, when the family moved to Barrymore Castle at Castlelyons. Barrymore Castle was destroyed by fire in 1771 during the tenure of the sixth Earl. The fortunes of the later family were subsequently weakened and dissipated by the seventh and eighth Earls. The family’s territorial and political importance therefore declined, although its name remains associated with medieval and early-modern Welsh and Irish history, place names, castles, aristocratic titles, and genealogical traditions.
History
The de Barry family emerged from the Norman expansion into Britain in the eleventh century. Odo de Barry, remembered as the family’s founder, received estates in Pembrokeshire and around Barry in south Wales after serving in the Norman conquest of England and the advance into south-east Wales. The family’s name was connected with Barry Island and the surrounding district. Gerald of Wales, a grandson of Odo and one of the most important Welsh writers of the twelfth century, preserved a traditional explanation linking the name to the island of Barri and Saint Baroc. Odo’s son William FitzOdo de Barry consolidated the family’s Welsh position. His lands included the extensive manor of Manorbier, together with Jameston, Manorbier Newton, Begelly, and Penally. A first motte-and-bailey fortification was built at Manorbier, and William is associated with the later stone rebuilding of Manorbier Castle. The family retained the lordship until the fifteenth century. William’s sons included Robert, Philip, Walter, and Gerald, the last being Gerald of Wales. Through this generation, the family’s Welsh and Irish histories became closely connected. The Irish phase began during the Norman invasion of Ireland. Robert de Barry accompanied Robert Fitz-Stephen, his maternal half-uncle, and participated in the siege of Wexford. He died at Lismore in 1185. Philip de Barry came to Ireland that year to support Robert Fitz-Stephen and Raymond FitzGerald in campaigns to recover lands in southern Ireland. The territories associated with Philip included Killede, Olethan, and Muscarydonegan, areas broadly corresponding to parts of modern County Cork. Olethan represented the former Uí Liatháin territory, while Muscarydonegan is connected with the modern barony of Orrery and Kilmore. Royal recognition followed the family’s military and political involvement. Robert de Barry was ennobled in 1181 as Baron Barry of Olethan and Ibawne. In 1206, King John confirmed Philip’s son William in possession of the family territories and granted him the lordships of Castlelyons, Buttevant, and Barry’s Court. These grants made the de Barrys one of the principal Anglo-Norman landholding families in eastern County Cork. The family also supplied officials to the English administration in Ireland. David de Barry became chief justice of Ireland in 1267, and another William de Barry served as justice in eyre between 1289 and 1294. In 1385, John Barry received the viscountcy of Buttevant. The family reached a further level of aristocratic distinction in 1627, when David Barry was made Earl of Barrymore by Charles I. Their residences reflected their changing power. Barryscourt Castle near Carrigtwohill was the principal family seat from the twelfth century until 1617. The family then moved to Barrymore Castle at Castlelyons. In 1771, during the time of the sixth Earl, Barrymore Castle burned down. The later family’s financial and social position deteriorated as the seventh and eighth Earls dissipated the remaining fortunes. The de Barrys maintained relationships with neighboring Irish elites, especially the MacCarthy Reaghs of Carbery and the MacCarthys of Muskerry. Intermarriage occurred between the families, and some branches of the de Barrys became heavily Gaelicized. Later traditions attempted to construct a Gaelic paternal ancestry for some Barrys, connecting them with Fothach Canann and the Dáirine or Corcu Loígde. The family’s historical legacy consequently combines Norman conquest, Welsh landholding, Irish colonization, aristocratic government, cross-cultural marriage, and the gradual decline of a landed noble house.
