The Hampdens were a long-established landed family in Buckinghamshire, with estates centred on the western edge of the Chilterns. Their seat at Great Hampden was situated about five miles south-west of Wendover. Members of the family had been knights of the shire on ten occasions and sheriffs of the county 17 times.
The eldest son of William Hampden, Member for East Looe in 1593, and Elizabeth, daughter of Sir Henry Cromwell of Hinchingbrooke, Huntingdonshire, Hampden was probably born in the spring or summer of 1595. His father died early in April 1597, shortly after the birth of his second son, Richard, leaving Elizabeth to secure John’s wardship and settle his debts. In his will, William placed his trust in his relatives, in particular his brother, Edmund; his cousins, William Hampden of Emmington, Oxfordshire and the rising lawyer George Croke† of Chilton, Buckinghamshire; his father-in-law Sir Henry Cromwell; his wife’s aunt, Joan Warren, and her husband; and his brother-in-law Sir Jerome Horsey*.
Elizabeth Hampden appears to have had musical tastes,
Hampden married Elizabeth, daughter of Edmund Symeon of Pyrton, in Oxfordshire, in June 1619. The Symeons were prosperous yeomen who had crossed the social boundary into the gentry in the late sixteenth century.
Hampden may have disappointed his mother in not seeking to buy a peerage in 1620.
The financial problems facing the Crown forced Charles I’s regime to turn to benevolences and Privy Seal loans to fund its wars. Hampden paid £10 of the Privy Seal loan of £13 6s. 8d. required from him in 1626.
This experience appears to have radicalized Hampden. He certainly seems to have been much more active in the Commons in 1628-9 than in previous parliaments. In the first session, he was appointed to committees on bills prohibiting recusants sending their children to be educated abroad (21 Mar. 1628), dealing with the peace of the church and commonwealth (7 Apr.), and against scandalous ministers (19 April).
Hampden himself regarded threats of innovation in religion and of alteration in government as linked. On 5 June 1628, after the king’s first, unsatisfactory answer to the Petition of Right, he argued that Charles should be informed of the House’s fears in both areas and its belief that the duke of Buckingham was the friend and relative of papists and the source of their apprehensions.
By the end of this Parliament, Hampden was a more prominent figure than he had been a year earlier. He had articulated concerns over royal policies shared by many much better known members and had almost certainly become more closely associated with them. Hampden was to prove a firm friend to Eliot in the years before the latter’s death in the Tower,
Hampden was undoubtedly a man of considerable wealth. He was able to pay a portion of £2,500 for his daughter Elizabeth’s marriage to Richard Knightley†, son of one of his oldest friends, and a further £1,000 with an extra £1,000 to come for his daughter’s Anne’s marriage to the younger Sir Robert Pye†. His will envisaged that his executors, (Sir) Gilbert Gerard* and his mother, should raise £14,000 from his estate to settle his debts, to raise portions for his remaining daughters and to pay small annuities to his younger children.
Hampden was wounded during a skirmish with royalist forces at Chalgrove Field on 18 June 1643, and died at Thame on 24 June. He was buried in Great Hampden on 25 June 1643.
