Sir Thomas Proby, 1st Baronet

Sir Thomas Proby, 1st Baronet (18 October 1632 – 22 April 1689) of Elton Hall, Huntingdonshire (now Cambridgeshire) was an English politician who sat in the House of Commons between 1660 and 1685.

Early life and ancestry Thomas Proby was the son of Sir Heneage Proby (of Elton and Raans, Buckinghamshire) and his wife Ellen Allen, daughter of Edward Allen, of Finchley, Middlesex. His paternal grandfather was the politician Sir Peter Proby, who had been a Member of Parliament (MP) Kingston upon Hull and Liverpool, as well as Lord Mayor of London.

Proby matriculated at Emmanuel College, Cambridge in 1648 before receiving legal training at Middle Temple. He was called to the bar in 1658. In 1679 he was elected MP for Huntingdonshire and sat until 1685.

Proby bought the Elton Hall estate following his marriage to Frances. Initially finding the estate in ruinous conditions, Proby went on to rebuild the manor completely around 1663 to 1666.

Proby died on 22 April 1689 at the age of 56, and his baronetcy became extinct. Elton Hall was under the ownership of Proby's widow until her death in 1699 before passing on to his brother, John Proby.
