There was more than one branch of the Cheyne family in Cambridgeshire in the early fifteenth century, but Laurence’s ancestry is reasonably discernible. By the 1240s, a Cheyne held the manor of ‘Cheyneys’ at Long Stanton, which passed down successive generations to the MP’s father. Sir William Cheyne was probably the man who was twice sheriff of Cambridgeshire and Huntingdonshire in Richard II’s reign and helped to suppress the Peasants’ Revolt. His eldest son and heir, John, held ‘Cheyneys’ in Henry IV’s reign, but died sometime between 1428 and 1436.
Cheyne married in his mother’s lifetime, taking for his bride the widow of the Hertfordshire knight Sir Philip Butler in early 1422. Elizabeth Butler’s father was the eminent judge, John Cockayne, for whom her new husband subsequently acted as an executor when he died seven years later.
Cheyne was himself elected as a knight of the shire on at least four occasions. He was more than qualified to sit in the Commons, since subsidy assessments of 1436 and 1450 valued his estates at £106 and £130 p.a. respectively.
Later in the same decade, Cheyne was a leading protagonist in the controversial Cambridgeshire election to the Parliament of 1439. The established political force in the county at this time was John, Lord Tiptoft†, but it appears that some of its gentry had become dissatisfied with his dominance. Although associated with Tiptoft in a land transaction as recently as June 1439, Cheyne and two other leading gentry of the shire, William Allington II* and William Cotton*, had allied themselves with the peer’s young rival, Sir James Ormond (or Butler), later earl of Wiltshire, by the time Parliament was called. They and other followers of Ormond appear to have engaged in large-scale canvassing – probably a mixture of threats and promises – against the candidates linked with Tiptoft. A first attempt to hold the election on 16 Nov. was aborted, but on the 19th Allington and Cotton were elected. Despite Tiptoft’s defeat, the feud between him and Ormond continued, but whether Cheyne involved himself in its later stages is unknown.
The election of Cheyne to at least four Parliaments is one mark of his local importance; another is his prominence in local administration. Early in his career, his wife’s interests in Hertfordshire and Bedfordshire gave him a role in the government of those counties. Subsequently, he served two terms as sheriff of Cambridgeshire and Huntingdonshire and regularly gained appointment to ad hoc commissions. Although never a member of the quorum, he was the most regular attender at the quarter sessions throughout his career as a Cambridgeshire j.p.
Between his third and fourth Parliaments, Cheyne was a feoffee of a family settlement involving other descendants of the Engaines, Mary the wife of Robert Stonham* and her daughter, Elizabeth, who had married the Bedfordshire esquire, John Broughton.
Among the feoffees of the settlement of 1449 were men for whom in turn Cheyne performed the same role: his son-in-law John Say,
During his later years, Cheyne continued to play a full part in local affairs, in spite of obtaining a second exemption for life from local offices in 1453.
Worth noting among Cheyne’s personal affairs in his later years are a series of trespass suits as both plaintiff and defendant against Richard Bonyfaunt, also of Fen Ditton, who had pursued a career as a London mercer.
