[1] By the marriage of his daughter Isabella Machell (1670–1764) to Arthur Ingram, 3rd Viscount of Irvine, he became the grandfather of the fourth, fifth, sixth, seventh and eighth Viscounts of Irvine, and great-grandfather of the ninth, seated at Temple Newsam near Leeds, whose family inherited and augmented his valuable property of Hills house at Horsham, and continued the parliamentary tradition there.
[2] Mathew's father John (1580–1647) married Jane, daughter of Sir Nicholas Woodroffe of Poyle, Surrey, in 1599,[3] and, developing his London and East India Company commercial interests,[4] and having established himself in Wendover, Buckinghamshire,[5] remarried in 1624 to Lady Elizabeth Aungier of Great Tangley, near Wonersh, Surrey, daughter of Francis Aungier and his first wife Douglas Fitzgerald (sister to Gerald FitzGerald, 14th Earl of Kildare).
[10] Mathew had been apprenticed a Goldsmith in London to the royal silversmith Edward Sewster, who died in 1628 granting the uncompleted term of service to his apprentice.
[11] Mathew and Elizabeth had three children, christened by Stephen Geree at Wonersh, of whom John Machell, born 1637,[12] was the only one to survive infancy.
[35] Licence was obtained for John Machell's marriage to Prudence Butler of Amberley Castle on 30 March 1661,[36] but it did not take place.
[37] Being indicted and found guilty, Machell was fined £1000 and Tully £500, they were imprisoned for a month, and bound in securities for good behaviour for seven years.
[39] In December 1666 Machell married Helena, daughter of Gervase Warmestry, registrar of the Worcester diocese, and step-daughter of Sir John Covert,[40] who was elected an M.P.
[44] His cousin John Machell was meanwhile active in the elections at Wendover, where the Hampden family maintained a strong presence.
His father Mathew died, having modified his will to take account of properties burnt in the Great Fire, now prime building land in the city.
John's half-brothers Joseph (citizen and Grocer of London[48]) and Mathew Machell now had families of their own, and their sister Anne became engaged to William Newman in 1679,[49] soon after his carvings for St Stephen Walbrook were completed and introduced.
[50] John advanced his elder daughter Isabella, and as of St Benet Gracechurch, in October 1685 (when she was 15),[51] married her to Arthur Ingram of Temple Newsam, 3rd Viscount of Irvine (aged 19), a grandson of Edward Montagu, 2nd Earl of Manchester.
Among his parliamentary contributions he advocated the rights of Quakers to make solemn affirmations instead of taking the Oath, attacked the severity of James II's judiciary, and spoke against other oppressive measures.
[61] An acknowledgement of this wish was made by the eldest grandson Edward Machell Ingram (who, as master of Temple Newsam, never inherited Hills), but not by Rich or his successors, more than one of whom served as MPs for Horsham.
