Lambert’s family was originally from Norfolk but had acquired property in Wiltshire, Gloucestershire and Dorset. His grandfather, a London Grocer, purchased the Wiltshire manor of Keevil in 1560, followed by Boyton and Sherrington manors in 1572.
Lambert almost certainly owed his election for Hindon, a borough which lay a few miles to the south of Boyton, to the 2nd earl of Castlehaven (Sir Mervyn Audley alias Tuchet*), to whom he was related by marriage. His mother-in-law had taken as her second husband Sir James Marvyn†, whose estate of Fonthill Gifford and electoral interest at Hindon had descended to Castlehaven, his grandson and heir.
Lambert was appointed in 1625 to Wiltshire’s commission of the peace, on which he was unusually active, serving regularly on all four annual sessions.
Lambert died in Boyton on 30 Aug. 1638 and was buried in the parish church on the following day.
