Eastcote is a suburban area in the London Borough of Hillingdon, in northwest London. In the Middle Ages, Eastcote was one of the three areas that made up the parish of Ruislip, under the name of Ascot. The name came from its position to the east of the parish. While no historically significant events have taken place in Eastcote, there are links to past events in the history of Britain. One such example is of Lady Mary Bankes, who lived in Eastcote for a time, and led the defence of Corfe Castle in Dorset against the Roundheads during the English Civil War. Eastcote also housed an outstation of the Bletchley Park codebreaking activities during the Second World War, with several codebreaking computers in use. This operation became the precursor to GCHQ, which remained in Eastcote after the war until the department moved to purpose-built buildings in Cheltenham in 1952. By the turn of the 20th century, the recorded population was around 600; this had reached for the ward in 2007. Part of Eastcote is in the Pinner postal district, despite being in Hillingdon rather than Harrow. History Toponymy Eastcote was originally recorded as Ascot, one of the three medieval tithings of the parish of Ruislip, along with Westcot and Norwood. Norwood, in the north of the parish, became Northwood; Westcot, in the west became Westcote (the main Ruislip village), and Ascot, in the east, became what is now Eastcote. Early developments The Hawtrey family moved to Eastcote around 1525 after Ralph Hawtrey married Winifred Walleston. She lived in a cottage named "Hopkyttes", which the couple moved into and renamed Eastcote House. A dovecote was built by their son John, without applying for a licence from the manor, as was the custom at the time. After his death in 1593, his nephew Ralph Hawtrey applied for the licence, which was approved. Ralph Hawtrey's only daughter became Lady Mary Bankes when she married Sir John Bankes, Chief Justice to Charles I. As a Royalist, she defended their home in Dorset, Corfe Castle, against the Roundheads in 1643 at the time of the English Civil War. A plaque on the south wall of St Martin's Church in Ruislip commemorates her heroic act. Lady Bankes had also lived at Haydon Hall in Eastcote, and her name is remembered by the school in Northwood Hills. In 1565, a land survey was completed which recorded 62
