Thomas Fitz-Christopher Plunket
Sir Thomas Fitz-Christopher Plunket was a leading Irish lawyer and judge of the fifteenth century who held office as Lord Chief Justice of Ireland. He was an ancestor of the Duke of Wellington in the female line. His second marriage to the heiress Marian Cruise inspired the ballad The Song of Mary Cruys.
Family
Thomas was born about 1407 in County Meath, third of the seven sons of Sir Christopher Plunket, who married Janet Cusack in 1403, the heiress of Killeen Castle, Dunsany.Thomas's brother Christopher was the 1st Baron Dunsany.
Thomas's sister Matilda "Maud" Hussey Artois Talbot Cornewalsh was "the Bride of Malahide".
Thomas's nephew Christopher was the 1st Baron Killeen. Both founded prominent Anglo-Irish dynasties. It was said that Thomas was "bred to the law": he and his younger brother Robert were the first two of numerous lawyers and judges in the Plunket family.
Another of Thomas's nephews was Sir Thomas Plunket of Dunsoghly Castle, Chief Justice of the Irish Common Pleas. This second Sir Thomas was the son of Sir Robert Plunket, who was briefly Lord Chief Justice in 1447.
Career
Thomas became Serjeant-at-law (Ireland) in 1434. At that time the holder of this office was the senior legal adviser to the Crown. He was entrusted with levying subsidies in 1447, and with surveying the royal mines in 1450. He was made a justice of assize in County Meath, and was entrusted with the defence of the county in 1456. There is good reason to believe that he was admitted to Lincoln's Inn in 1452-3, although the name is spelt "Blonket" in the records.During the Wars of the Roses Thomas, like most of the Anglo-Irish gentry of the Pale, was a supporter of the would-be King Richard of York; he accompanied him to England in 1460 and was knighted. After the triumph of York's son, King Edward IV in 1461, Plunket was appointed Lord Chief Justice, but was forced to contest the position with his predecessor, Sir Nicholas Barnewall. He was reappointed in 1463 and confirmed in office in 1468, jointly with John Chevir.
In 1462, as a mark of royal favour, he was allowed to take twelve trees from Trim Park.
He died on 12 June 1471, bequeathing the sum of £100 to Christ Church Cathedral, Dublin. He was buried in Rathmore Church, Rathmore, County Meath, where an impressive tomb was erected to the memory of Thomas and his second wife Marian Cruise. Rathmore Church is now a ruin, but the tomb, with the effigies of the couple, is still visible. The effigy of Thomas, wearing a suit of armour, is in good condition; Marion's has decayed badly.
