More was born at Hurstmonceaux, the home of his maternal grandfather Sampson Lennard*. Either his father, Sir Robert More, or his grandfather, Sir George More, represented Surrey in every Parliament in this period except the last. In 1621 John Shaw, the vicar of Woking in Surrey who had been deprived for nonconformity in the 1590s, dedicated a synopsis of the Bible written in Latin verse to More.
More was re-elected with Carew in 1625. It was probably he, rather than Edward Moore, who was named to the committee for a bill to enable the trustees of his relative the 4th earl of Dorset (Sir Edward Sackville*) to sell lands to settle debts, particularly as his name follows that of his grandfather Sir George.
More’s father died shortly before the Parliament assembled and, as More himself was still under age, his mother purchased his wardship for 200 marks.
I hear when you fell you were scarce sober, which troubles me much to think that you should live so beastly a life that the country should take notice of it, and so soon to forget those good instructions that your blessed father which is in heaven taught.

Nevertheless Sir George More would later express bitter disappointment that his grandson was not made a deputy lieutenant.
More was elected in 1628 for Guildford, which had previously returned his father and grandfather. Although not mentioned in any of the surviving records of the third Caroline Parliament, he evidently followed the debates concerning the Petition of Right with interest. In an undated letter to his mother he wrote that there was little he could tell her about proceedings in the Commons ‘either good or bad’ because ‘we are still about the old matter concerning the liberties of the subject’. He stated that they ‘hope[d for] the best’, but the outcome was still uncertain. In addition, copies made by More of speeches and other documents relating to the Petition survive among the family papers.
More wrote twice to his grandfather in the 1629 session giving news of proceedings in the Commons. In the first, which probably dates from late January 1629, he apologized for having little to tell because, for although the House had ‘spoken of many businesses’, it had ‘brought none to a conclusion’. More stated that ‘our religion’, particularly ‘the depressing of popery and Arminianism’, was ‘the grand business now in hand’. However he also informed Sir George of the dispute over the payment of Tunnage and Poundage and sent him a copy of the king’s speech of 25 Jan. on that subject. In a postscript the next day, he added news of the Commons’ decision to defer the reading of the Tunnage and Poundage bill ‘until the business of religion be somewhat nearer drawn to an end’.
In the summer of 1630 More and his cousin Carew fled overseas to avoid their creditors. On 16 July Carew’s father, Sir Nicholas Carew alias Throckmorton*, wrote to his son warning that just as More ‘was a companion with you here in your unthrifty and careless courses, so likewise he will be there’.
