Leigh’s family sprang to prominence in Warwickshire in the mid-sixteenth century, when his great-grandfather, a successful London Mercer, made extensive land purchases there, including the manor of Stoneleigh, a few miles south of Coventry. The old merchant spawned two significant gentry lines in the county. The junior, based at King’s Newnham, was represented in the early seventeenth century by Sir Francis Leigh I* and Sir Francis Leigh, 1st bt*. Stoneleigh became the principal seat of the senior branch, headed at the start of James’s reign by the prominent figure of Leigh’s grandfather, Sir Thomas, custos rotulorum of Warwickshire, and a baronet from 1611.
Leigh resided at Leighton Buzzard until at least the early 1620s, serving several times as a local subsidy commissioner. However, his recruitment as a Staffordshire j.p. in 1623, and his addition to the oyer and terminer commission which covered the county, implies that he had relocated to Hamstall Ridware, and indeed he was removed from the Bedfordshire bench shortly afterwards.
In 1628 Leigh was elected junior knight of the shire for Warwickshire, but on 20 Mar., three days after the Commons assembled, the sheriff was summoned to explain why he had still not returned the indenture, thereby preventing Leigh from taking his seat. The significance of the delay is unclear. Leigh failed to leave any direct trace in the parliamentary records, but doubtless took a close interest in the abortive investigation, launched by the Commons on 13 June, into the two recent commissions for recovery of debts owed to the Crown, since he headed the long list of commissioners appointed on 17 May 1628. The scale of Leigh’s involvement in this project is unclear, and his prominence on the list may have been due simply to his social status, which surpassed that of most of his colleagues.
As sheriff of Warwickshire in 1636-7, Leigh managed the collection of Ship Money somewhat more smoothly than his predecessor, (Sir) Greville Verney*, despite spending at least part of his shrievalty in Bedfordshire. Nevertheless, at the end of his term the county was £834 in arrears on the 1636 writ, and of this sum £484 remained unpaid in November 1639.
