Thomas Somerset (born by 1529, died 6 April 1586[1]) was an English Roman Catholic layman, kept imprisoned for long periods by Elizabeth I of England.
On 27 June 1562, he was summoned before the Lords of the Council at Greenwich, who expected "an humble submission, for wante whereof, and for that he seamed to go about to justifye his cause, he was returned to the Flete, there to remaine until he" should "have better considered of himself".
After an imprisonment of close on twenty years he was released on bail, 28 February 1581-82, to attend to legal business in Monmouthshire.
By 22 October 1585, suspected of complicity with Mary Queen of Scots,[1] he was in the Tower on a charge of high treason.
Being possessed of properties in Gloucestershire and Monmouthshire, he paid the costs of his imprisonment, and his name therefore is not to be found in the Tower Bills.
