Sir Samuel Grimston, 3rd Baronet

Sir Samuel Grimston, 3rd Baronet (7 January 1643 – October 1700) of Gorhambury House, Hertfordshire was an English politician.

During the reign of James II he remained in private life, being, it is said, much disliked by the king, who expressly excepted him from pardon in the manifesto he issued when he contemplated landing in England (1692).

[3] Grimston succeeded to his father's baronetcy and estates, including Gorhambury, in 1683, and was returned a member of the Convention Parliament of 22 January 1689.

She had left her estate of Froxfield Manor as an endowment to the almshouses she had created which were called the Duchess of Somerset's Hospital.

[4] Grimston who was one of the trustees of the Duchess's will refused to convey the prescribed lands and income to the hospital until he was ordered to do so by the Court of Chancery.
