Although little is known of Foxton’s background, his father was a Cambridge alderman sufficiently wealthy to furnish him with a gentleman’s education at Cambridge University and the Middle Temple.
Elected to the 1621 Parliament for Cambridge during his first mayoral term, the validity of Foxton’s election was challenged on 22 Mar. by Sir Robert Phelips, who claimed that Foxton had abused his position by returning himself. He also noted that the attendance of mayors at Westminster hindered the administration of corporate towns.
Foxton remained active in the corporation throughout the 1630s and 1640s. It was largely through his efforts, and those of the recorder, Talbot Pepys*, that Cambridge raised a Benevolence in 1630-1 following a severe outbreak of the plague.
Foxton resigned from the corporation in 1646 and made his will on 16 Nov. 1648. He died, childless, shortly thereafter, and was buried on 8 Dec. in Great St. Mary’s, Cambridge. His ‘next heir’ was a nephew, Nicholas Craddocke, who received £100 and Foxton’s lands in Great Shelford. To another nephew, William Craddocke, he left an inn in Cambridge town centre. Emmanuel and Caius colleges received £10 each and the University library benefited by £40.
