The Grimstons identified their earliest ancestor as Sylvester Grimston, who held land in Yorkshire after the Conquest.
Raised a Calvinist by his father, who held sublapsarian views on predestination,
In 1614 Grimston was elected to Parliament for Harwich, which lay just over three miles west of Bradfield. His decision to serve at Westminster may have been prompted by fears that his newly purchased title would be attacked in Parliament. Certainly his surviving papers include copies of ‘A Collection of the chief things belonging unto Baronets’, a proposed petition to the king in favour of abolishing the order of baronetcy, and the ‘Motives to induce ... the Commons House ... to petition His Majesty’ for its abolition, which was read in the Commons on 23 May.
Grimston served as sheriff of Essex in 1614-15, and was later fined £5 for a failure in connection with his duties.
Grimston was summoned before the Privy Council in February 1622 to explain his failure to contribute towards the Palatinate Benevolence, and was subsequently induced to donate £40.
In May 1625 Grimston was appointed a deputy lieutenant for Essex. Following the outbreak of war with Spain he alerted his superiors to the parlous state of Harwich’s defences, whereupon he was appointed, without his knowledge, co-treasurer for repairing the fortifications by Essex’s joint lord lieutenant, the 2nd Earl of Warwick (Sir Robert Rich*). In the event, the money for rebuilding Harwich’s defences and constructing a new fort at Landguard Point was received and disbursed by his fellow treasurer, Richard Scott.
Following the collapse of the 1626 Parliament, Grimston was punished for his association with Warwick, whom Buckingham had counted among his enemies ever since the failure of the York House Conference. On Warwick’s removal as joint lord lieutenant of Essex early in September 1626 Grimston was excluded from the county’s deputy lieutenancy at Buckingham’s behest despite opposition from the newly restored lieutenant, the 5th earl of Sussex.
Grimston’s final release was not ordered until the general amnesty of 2 Jan. 1628.
to commit without a cause is great injustice, for the cause of commitment ought ever to precede; for after a man is committed his house may be searched, an unlawful book may be found and a man may be questioned for that which at the first was never intended. I speak this because I have known it so.

One week later he expressed dismay that even though the House had voted that none could commit without showing cause, Secretary Coke (John Coke) had maintained that it was essential for the Crown to retain this power. Unless Parliament took action, he added, ‘I think I shall be quickly where I was this time twelvemonth - in prison’.
Beyond his pronouncements on arbitrary imprisonment, Grimston seldom spoke that session. However, on 4 Apr. he announced that he favoured granting four subsidies, and on 23 May he proposed that the speeches made by Glanville and Marten that morning at a joint conference with the Lords be copied and distributed to each Member.
Grimston undoubtedly welcomed the news of Buckingham’s assassination, not least because it was quickly followed by his restoration to the Essex bench. He played only a marginal role in the 1629 session, receiving just three mentions in the records. These concerned his appointments to committees to provide an enlarged preaching ministry (23 Jan.), to prevent the begging of forfeitures before attainder (23 Jan.) and to halt the sending of victuals to Spain (26 January).
Grimston fell foul of High Commission in 1631 for supporting the corporation of Harwich against its puritan minister, William Innis, for which offence he was arraigned before the Privy Council in January 1632.
