Baron of Navan
The Barony of Navan was an Irish feudal barony which was held by the de Angulo family, whose name became Nangle. It was a customary title: in other words the holder of the title was always referred to as a Baron, and this privilege was hereditary, but the Baron was not a peer in the strict sense, and was not entitled to a seat in the Irish House of Lords. The title was conferred by Hugh de Lacy, Lord of Meath, on his trusted lieutenant Jocelyn de Angulo, in or about the year 1172. Jocelyn is thought  to have taken his surname from his birthplace at Angle, Pembrokeshire. Junior branches of the Nangle dynasty founded the Nagle and Costello families. Jocelyn acquired not only Navan but also Morgallion and Ardbraccan. His building of Navan Fort is generally regarded as marking the foundation of the town of Navan. Jocelyn's son Gilbert de Angulo, the 2nd Baron, rebelled against Richard I in 1195. He was attainted and his estates declared forfeit to the Crown; but he was later pardoned by King John. He was killed in a skirmish in 1212 or 1213. The family acquired wealth and substantial  lands, but they played a curiously obscure role in Irish history. John Nangle, 16th Baron of Navan, like most of the Anglo-Irish nobility of the time, supported the Yorkist pretender to the Crown, Lambert Simnel, and after the defeat of Simnel's cause at the Battle of Stoke, he shared in the general pardon issued by Henry VII of England. Described as a "lusty warrior", he fought on the winning side at the Battle of Knockdoe in 1504. Patrick, 18th Baron, was one of the Anglo-Irish nobles of the Pale who were involved in the "cess controversy" of  1577, concerning the Crown's right to levy taxes for the upkeep of garrisons, and was briefly imprisoned for non-payment of the tax. Peter Nangle, a younger son of Thomas, 17th Baron, was in the entourage of Hugh O'Neill, 2nd Earl of Tyrone and played some part in the events leading to the Flight of the Earls. In the early seventeenth century the family increased their influence by marrying into powerful "New English" families like the Boltons and Loftuses. Thomas, 19th Baron, took part in the Irish Rebellion of 1641, and signed the "Catholic Remonstrance" issued at Trim, County  Meath in March 1642 addressed to King Charles I of England. As a result, he was attainted as a traitor and forfeited much of his property. Although his son George, 21st Baron (who succeeded his brother Patrick), recovered part of the family estates at the Restoration of Charles II, the family's fortunes had begun to decline. John, 21st Baron, was a supporter of James II of England: after the Glorious Revolution he was attainted and the Nangles left Ireland for good. Patrick, 23rd Baron, was a soldier in the French Army, and supporter of the Old Pretender. Francis, 24th  and last Baron, spent many years serving in the Austrian Army; he died unmarried in Vienna in 1781, when the title became extinct.
