The founder of the Clayton family’s fortunes was Robert Clayton (1629-1707), a Northamptonshire carpenter’s son who rose to become the leading broker and wealthiest citizen of London. He was knighted in 1671, and acquired, with other property, Surrey estates at Marden and Bletchingley. He was succeeded to these by his nephew William Clayton, Member for Bletchingley from 1715 until his death in 1744, who was created a baronet in 1732 and bought the Buckinghamshire manors of Harleyford and Marlow, together with houses in the latter borough. He devised the Marden estate and Bletchingley property to his elder son Kenrick Clayton (c.1715-69), Member for Bletchingley from 1734 to his death, who was succeeded as 3rd baronet by his only son Robert Clayton (?1740-99), a Whig Member of Parliament, 1768-84 and1787-99.
This William Clayton, who was born in about 1718, was Member for Bletchingley, 1745-61, and Great Marlow, 1761-83. His second wife Caroline Lloyd, the mother of his first son William, brought him an estate at Alltycadno in Carmarthenshire. With his third wife Louisa, daughter of the 1st earl of Pomfret, he had a son George, who settled at Stone Hall, near Westerham, Surrey. William Clayton inherited from his father the lease of the 86-acre demesne manor of Kennington, across the Thames from Westminster, which belonged to the duchy of Cornwall. It had been in the hands of the Claytons since 1661 and had been renewed at intervals. In 1776 Clayton, perceiving that the property was bound to increase in value with the urbanization of south London, obtained a private Act of Parliament which empowered him and his heirs to grant building leases on it. The following year he secured a renewed lease, at the old rent of £16 10s. 9d., and on payment of a fine of £468, for 99 years on the lives of his two sons and one James Medwin. Development of the north-eastern segment of the manor was well advanced by the time Clayton died in 1783.
Clayton had five sons, of whom William, the eldest, entered the army. In 1812 he went with the Horse Guards to the Peninsula, and the following year he commanded squadrons at the battles of Vitoria, the Pyrenees and Pamplona. He saw action at Quatre Bras and Waterloo in 1815. A shadow hung over his conduct on the latter occasion, in that ‘having left the field as wounded, the surgeon of the regiment could not return him in the list of wounded’; but the duke of Wellington was prepared to believe that there had been extenuating circumstances, and Clayton’s subsequent promotions were not affected.
While this dirty linen was being washed in public, Clayton had been trying to revive the family interest at Great Marlow, where the pro-Catholic Williamses of Temple House, in control since 1796, had faced a serious independent challenge to their authority in 1826. Seeking to exploit anti-Catholic feeling in the borough, Clayton forced through a petition against Catholic claims at a town meeting, 24 May 1827. He built new houses to accommodate tenants evicted by the Williamses in reprisal for voting against them and in 1828 promoted a successful campaign to open the vestry and parish accounts.
the noblest, the best, and the boldest scheme of legislation which had been brought into Parliament since ... 1688 ... It certainly deals a deadly blow to arrogance and usurpation ... and in taking great power from a few, it divides it amongst the great mass of the middle classes.
He admitted to some reservations over ‘minor details’, but contended that the bill had been ‘framed for healing great distempers and for securing liberty and repose’. He attacked the Williamses for voting against its second reading, and argued that reform would ‘prevent any further increase’ in expenditure and taxation. He presented the address to the king, 20 Apr. 1831. He stood again for Marlow at the ensuing general election with every confidence of success, led the poll for two days, but finished five votes behind the younger Williams. He demanded a scrutiny, but it did not benefit him, and he did not carry out his threat to petition.
Quite apart from the problems connected with the Kennington lease, Clayton’s father’s financial affairs were beset with difficulties. He had let Marden to Joseph Buonaparte and taken up residence at Boulogne, where he died, 26 Jan. 1834. His personalty was sworn under £10,000, and his estate, of which administration was granted to Clayton, though he was not named as an executor in the will, was in chancery for several years.
