Petersfield was a non-incorporated borough, owned by the Weston family until they sold it in 1597 to Thomas Hanbury, an Exchequer official.
Thomas Hanbury returned his son, also Thomas Hanbury, to the 1597 Parliament, the first after his acquisition of the manor of Petersfield. He also nominated John Swinnerton in 1601, and probably William Kingswell, a Hampshire country gentleman, in 1597 and 1601.
With the exception of Thomas Chatterton, who has not been identified, all the remaining MPs for this period had their own connexions with the borough. George Rithe (1559), Thomas Dering (1563), John Cowper and Robert Rithe I (1571) all owned local estates. Richard Norton II came from a Hampshire family who owned a little property near the borough. Edmund Marvyn married into a Hampshire family, and took up residence in Petersfield, representing the borough in the first Parliament after his marriage, and the two subsequent Parliaments.
