The manor seems to have passed by 1434 to William Burgoyne of Roxton (Beds.) (d. 1456), whose son Richard died in 1464 leaving Caxton to his heir John, a minor. John presumably succeeded on coming of age c. 1478, but died in 1487, whereupon his feoffees granted the manor in the same year to Agnes Lane for life, with remainder to Richard Burgoyne, then a child. It appears that Richard died before coming of age, probably in 1504 or 1505, and Thomas son of John Burgoyne of Impington was said to hold the manor in 1506. By 1509, however, the property was held by the sisters of Richard Burgoyne, Margaret (d. 1529), wife of George Heveningham (d. 1530), and Elizabeth, wife of Thomas Thursby. By 1530 one half was still held by Thursby, the other half was divided between the three surviving daughters of Margaret Heveningham. On the death of one of those daughters without heirs in 1532 or 1533, the half manor was divided equally between the surviving sisters, Alice wife of Thomas Green and Anne wife of Sir Ambrose Jermyn of Rushbrooke (Suff.). Thursby sold a quarter of the manor to Jermyn in 1536. In or after 1549 the Greens' share passed to Jermyn, who at his death in 1577 left half the manor to his fourth son, Anthony. In 1578 another Thomas Thursby sold his family's share of the manor to Anthony Cage the elder (d. 1583), a London salter who already owned Longstowe.
