The Jurdeleys were a Buckinghamshire gentry family of middling status. The MP’s grandfather and namesake, who attested the Buckinghamshire elections of 1413 (May), 1416 (Mar.) and 1421 (Dec.), had served as a tax collector in the county in 1430, and was deemed sufficiently important to be required to take the general oath against maintenance in 1434.
John Jurdeley himself is first heard of in 1455, when he was among his father’s feoffees of property in West Molesey, Surrey, which the older man held in trust for the London ironmonger William Paxman.
