William ap Thomas
William ap Thomas (died 1445) was a member of the Welsh gentry family that came to be known as the Herbert family through his son William Herbert, 1st Earl of Pembroke and is an ancestor of the current Earls of Pembroke.
Raglan manor, attained through marriage through heiress Elizabeth Bluet, was greatly expanded by William and his son, William Herbert, into the well-fortified Raglan Castle, one of the finest late medieval Welsh castles.
William served King Henry V of England during his first French campaign and in numerous subsequent capacities and was knighted in 1426.
William ap Thomas was the son of Sir Thomas ap Gwyllym, Knt (d. 1438) of Perth Hir and Maud Morley, daughter and co-heir of Sir John Morley of Llansantffraed. In 1400 Thomas and his wife Maud inherited Llansantffraed Court, the country seat and estate of Sir John Morley. Llansantffraed Court was located approximately 2 miles west of the town of Raglan and Raglan Castle, near Clytha and Abergavenny, Wales. Thomas is buried in the church where a plaque records his death and that of his successors until 1624.
After Sir Thomas' death, Llansantffraed Court passed through William's brother, Philip. In 1449 Philip was given 'advowson of the living' by Sir Edward Nevill, 3rd Baron Abergavenny and Elizabeth de Beauchamp, Lady of Abergavenny. Llansantffraed Court was held by the Philip's descendants in an unbroken line until the 17th century.
The Blue Knight of Gwent
Sir William fought in France with Henry V of England and at the famous Battle of Agincourt. In 1415, Sir William was created knight banneret. In 1426, ap Thomas was knighted by King Henry VI, becoming known to his compatriots as "Y marchog glas o Went" (the blue knight of Gwent), because of the colour of his armour. he gradually began to establish himself as a person of consequence in South Wales.
Important Offices In Wales
William held the following positions:
- William was Steward of the Lordship of Abergavenny by 1421.
- He was appointed High Sheriff of Cardiganshire and Carmarthenshire in 1435.
- In 1440, he was appointed the position as High Sheriff of Glamorgan.
- In 1442 or 1443, William became Chief Steward of Richard Plantagenet, 3rd Duke of York's estates in Wales.
- Was a member of the Duke of York's military council.
While William played an active role for the Duke of York, his sphere of influence was generally limited to South Wales.
William married firstly in 1406 Elizabeth or Isabel Bluet (also spelled Bloet), the daughter of Sir John Bluet of Raglan manor and widow of Sir James Berkeley. Elizabeth, "the lady of Raggeland," inherited Raglan Castle with her husband James Berkeley, who later died in 1405 or 1406. Elizabeth died in 1420. Prior to Elizabeth's marriage to Berkeley she married and became the widow of Sir Bartholomew Picot. Elizabeth's third marriage to William ap Thomas had no issue.
William married secondly heiress Gwladys ferch Dafydd Gam, described by Welsh poet Lewys Glyn Cothi as 'The Star of Abergavenny' for her beauty. She was the daughter of Sir Dafydd Gam and the widow of Sir Roger Vaughan of Bredwardine. All three men had been part of the Welsh contingent that fought with King Henry V of England in France, including the Battle of Agincourt.
William and Gwladys had the following issue:
- William Herbert, 1st Earl of Pembroke (1423–1469) took the surname Herbert. William's allegiance to Richard, Duke of York, and Richard Neville, 16th Earl of Warwick, branded him Edward IV's Welsh "master-lock". He was the first full-blooded Welshman to enter the English peerage and he was knighted in 1452. He married Anne Devereux daughter of Sir Walter Devereux in 1449, by whom he had issue.
- Elizabeth married Sir Henry Stradling (1423–1476), son of Sir Edward Stradling (d. c.1394) and Gwenllian Berkerolles, sister and co-heir of his neighbour, Sir Lawrence Berkerolles. Reversing alliances from the previous generation, Henry and his brothers-in-law were hostile to the Henry VI reign. Henry went on a pilgrimage to the Holy Land in 1476. Henry died on 31 August 1476 on his journey back to England and was buried at Famagusta, Cyprus. Thomas, Elizabeth and Henry's young son died on 8 September 1480.
- Margaret married Sir Henry Wogan, steward and treasurer of the Earldom of Pembroke, tasked with securing war material for the defence of Pembroke Castle. Henry and his father, John Wogan of Picton, witnessed an act of Bishop Benedict in 1418. Their son, Sir John Wogan, was killed at the battle of Banbury in 1465, fighting by the side of his uncle, William Herbert, Earl of Pembroke.
When Sir John Bloet died, Raglan manor passed to Elizabeth Bloet and her husband James Berkeley. When William's wife, Elizabeth died in 1420, Elizabeth's son Lord James Berkeley inherited Raglan Manor. William resided at Raglan manor as a tenant of his stepson until 1432 when he purchased the manor from Lord Berkeley.
Grandious expansion for defense and comfort occurred between 1432 when William ap Thomas bought the manor and 1469 when his son, Sir William Herbert, was executed. Improvements by father and son included the twin-towered gatehouse, five storied Great Tower encircled by a moat, a self-contained fortress in its own right, South Gate, Pitched Stone Court, drawbridge and portcullis.
- "The Earle of Penbroke that was created Earle by King Edward the four bult the Castell sumptuously at the first
- Not farre from thence, a famous castle fine
- That Raggland hight, stands moted almost round
- Made of freestone, upright straight as line
- Whose workmanship in beautie doth abound
- The curious knots, wrought all with edged toole
- The stately tower, that looks ore pond and poole
- The fountaine trim, that runs both day and night
- Doth yield in showe, a rare and noble sight"
Dafydd Llwyd proclaimed Raglan the castle with its "hundred rooms filled with festive fare, its hundred towers, parlours and doors, its hundred heaped-up fires of long- dried fuel, its hundred chimneys for men of high degree."
