3rd Lord Swinnerton. He inherited from his brother. He was in the King's service overseas in 1340. On February 18, 1341/42, he was sheriff of Shropshire and Staffordshire. He was knight of the shire for Staffordshire in 1343. In December, 1345, the sheriff of Staffordshsire was ordered to take into the King's hands all his lands and goods. There is no further mention of this incident; possibly it was the result of a default in some legal proceedings due to his absence abroad. He served in the King's retinue from the passage to La Hogue in 1346, and at the battle of Crecy, at Calais, and elsewhere. In 1347-1349, as Sir Thomas de Swynnerton, knight, doorkeeper of the king's hall, he was paid for the hangings provided for the hall. On October 14, 1357, the King gave 100 marks towards his ransom, he having been taken prisoner in Scotland.
