The early history of the estate later known as Swakeleys manor is obscure. In the early 13th century the estate seems to have passed to John de Trumpinton whose son, also called John, still held it about 1260. By 1329, however, part of this land had apparently been acquired by Robert Swalcliffe of Swalcliffe. Four years later Robert and his wife conveyed their lands to William le Gauger of London, but the family name Swalcliffe, later contracted to Swakeleys, continued to attach to the estate. In 1751 the estate was sold to the Reverend Thomas Clarke, Rector of Ickenham. Members of the Clarke family held Swakeleys for over a century. Thomas Clarke died in 1796 and was succeeded by his son Thomas Truesdale Clarke. Thomas Truesdale's son, another Thomas Truesdale, succeeded in 1840 and bought the manor of Ickenham in 1859. He died in 1890 and was succeeded by his son William Capel Clarke, who had married Clara Thornhill and had added his wife's name to his own. William Capel Clarke-Thornhill died in 1898 and in 1922 his son Thomas Bryan Clarke-Thornhill sold most of the Swakeleys estate to agents for development as a residential suburb.

The extent of Swakeleys in the Middle Ages is unknown: from the 14th century the manor included much land outside the parish. In 1531 it was said to comprise more than 1,000 acres and in 1608 over 2,000 acres. At inclosure in 1780 Thomas Clarke held 368 acres in Ickenham. A park is mentioned in 1453 and again in 1517. This presumably was that surrounding Swakeleys manor-house.
