Blayney

Castleblayney was founded by Edward Blayney, governor of Monaghan in the early 17th century, who was granted extensive estates in the Monaghan and Castle Blayney areas by King James I. He became Baron Blayney of Monaghan in 1621 and died 1629. However by the middle of the century the family was in difficult financial circumstances and the estate was sold to Thomas Vincent, a London merchant. By the marriage of the 4th Lord Blayney with Vincent’s daughter Elizabeth the estate returned to Blayney family possession. Much of their Monaghan estate was sold off in 1680 by the 5th Lord Blayney and passed through the Cairnes, Murray and Cunningham families until it was inherited by the Westenras who became the Lords Rossmore. Cadwallader 7th Lord Blayney sold part of the Castleblayney estate to the Uptons, Lords Templetown. Andrew Thomas the 11th Lord Blayney was a distinguished soldier who served in the Napleonic wars and developed the town of Castleblayney. He died in 1832. In 1853 the Castle Blayney estate in county Monaghan was purchased by Henry Thomas Hope from the 12th and last Baron Blayney, who died in 1874. The representatives of Lord Blayney, London, owned 1,561 acres in county Tipperary and 421 acres at Carrickfergus in the 1870s.
