Descended from a cadet branch of the Beaumont family of Coleorton, Beaumont was distantly related to his namesake, Sir Henry Beaumont I*. His grandfather was treasurer of the Inner Temple, acquired Gracedieu in north Leicestershire on the Dissolution of the Monasteries in 1539, and first sat for Leicester in the same year.
In 1597 Beaumont was admitted to his father’s inn, the Inner Temple, but he presumably did not start his legal studies in earnest until after he graduated from Oxford in 1600. He stood for election at Leicester in 1604 after he reminded the mayor (from the Inner Temple) that he had recently been made free of the borough so that he might be eligible to stand for Parliament.
Beaumont made 15 recorded speeches and was named to 42 committees during the 1604 session. He may have been late in arriving, as he was not mentioned in the surviving records until 18 Apr., when he was one of those who successfully opposed the bill to prevent outlaws from sitting in the House. Eight days later he was among those appointed to consider a replacement for this measure. He was also appointed to consider the bill to prevent secret outlawries on 17 May.
On 20 Apr. Beaumont was among those appointed to attend the king at Whitehall to hear his defence of the Union.
Beaumont supported composition for wardship, arguing on 16 May that it was perfectly reasonable to buy out this feudal due as Magna Carta had been secured by a grant of taxation.
On 11 May Beaumont was appointed to the committee to investigate William Tipper, who had been paid £100 to secure the passage of a bill establishing a monopoly of making hats. He reported on 15 May that Tipper ‘hath played the knave honestly’, for although the bond promising payment had preceded the preferment of the bill, Tipper had inserted a note in the margin stating his ‘misliking [of] it’. Further proceedings were deferred because of Tipper’s absence.
The Leicester corporation showed its appreciation of Beaumont’s services by presenting him with wine and sugar on his return to Leicestershire after the end of the session, and a further three quarts of sack and three quarts of claret on his marriage in October.
