Sir Thomas Tresham (died 8 March 1559) was a leading Catholic politician during the middle of the Tudor dynasty in England.
In 1540, he had licence to impark the Lyveden estate in the Aldwinkle St Peter's parish, where the "New Bield" erected by his grandson Thomas Tresham II still stands.
[1] In the same year, although his main estates were in Northamptonshire, it was noted that he had a house with twenty-nine household servants at Wolfeton in Charminster, Dorset.
He was named Grand Prior of England in the Order of Knights Hospitallers of St John of Jerusalem by Royal Charter dated 2 April 1557, qualifying him for a seat in the House of Lords.
He took his seat in the House of Lords in January, 1557–58, but sent a proxy to the first parliament of Queen Elizabeth, possibly due to illness.
