(died 1469), the third or fourth son of Sir David Mathew (died 1484) of Llandaf, inherited the land by marriage to Catherine, heiress of Radyr, and built Radyr Court, a manor house on the site of what is now the Radyr Court Inn in Danescourt. The house was used as a court. Although it was destroyed by a fire in the 19th century, the three large dungeons survived and can still be seen at the Inn. On Thomas' death, his lands passed to his eldest son David and then to his younger son William Mathew (died 1528), who was knighted by King Henry VII at the Battle of Bosworth in 1485. Sir William accompanied Henry VIII to the Field of the Cloth of Gold in 1520. His successor was his eldest son Sir George Mathew, who became MP for Glamorganshire and in 1545 Sheriff of Glamorgan. Sir George created a deer park that ranged far north of Radyr. Tenant farmers there were evicted, and the loss of rental income contributed to the decline in the family's fortunes. He had 24 children, eight of whom were illegitimate. Many were daughters, and Sir George needed large sums of money for their dowries. On his death Sir George's lands passed to his eldest son William, who also became an MP and invested in the Pentyrch ironworks. This was an astute move as feudalism was giving way to early industrialisation. William's descendants inherited a diminishing fortune. Captain George Mathew, the last of the family to live in Radyr, married Elizabeth Poyntz, and the couple left Radyr to live on her estates at Thurles in County Tipperary, Ireland in 1625. Stuart period Radyr's new owner was a wealthy landowner, Sir Edward Lewis, who was knighted by James I. Sir Edward owned St Fagans Castle and its surrounding lands, scene of the Battle of St Fagans in the English Civil War. The Lewis fortune passed to Elizabeth Lewis, who married Other Windsor [sic], 3rd Earl of Plymouth, the principal landowner in Cardiff, Penarth and Barry. A survey in 1766 shows that the Plymouth family owned the freeholds of most of Radyr. It continues to do so today. Plymouth Estates sold of residential land in Radyr in 2007.
