Thomas de Berkeley, 3rd Lord Berkeley, known as "The Rich," was born in 1293. In 1327 he was made joint custodian of the deposed King Edward II, whom he received at Berkeley Castle, but being commanded to deliver over the government to his fellow custodians, Lord Maltravers and Sir Thomas Gournay, he left there to go to Bradley "with heavy cheere perceiving what violence was intended." As an accessory to the murder of the deposed king, he was tried by a jury of 12 knights in the 4th year of King Edward III., but was honorably acquitted. He married about 1320 (1) Margaret Mortimer, daughter of Roger Mortimer, Earl of March, and in 1347, (2) Catherine Clivedon, widow of Peter le Veel, of Tortworth, co. Gloucester, and daughter of John Cliveton, of Charfield. This lord having adhered to the interests of the Queen, Mortimer, and Prince Edward, afterwards the third of that name, furnished "the only precedent," says Smith, "of a peer being tried by knights, as the peers would have been both judges and jurors." He first assumed a miter for his crest. He was summoned to parliament from June 14, 1329 to November 20, 1360.
