The Pophams, who could trace their lineage to the reign of Henry I, took their name from a village near Basingstoke, Hampshire. By the thirteenth century they had settled at Huntworth, Somerset, and in Elizabeth’s reign Popham’s father, Sir John, built a magnificent mansion at Wellington. This and several other properties in Somerset and Wiltshire were settled on Popham at his marriage in 1590.
On his return from the Cadiz expedition, during which he was knighted by the 2nd earl of Essex, Popham was appointed a colonel of the Wiltshire militia. He may have been negligent in some of his military duties, for at a muster held in early September 1605 his regiment was short of 100 men. The lord lieutenant, Edward Seymour, 1st earl of Hertford, was ‘much incensed’ and replaced Popham with Sir William Button*.
In the aftermath of the Gunpowder Plot, Popham was appointed to a committee to prevent further conspiracies (21 Jan. 1606).
Popham was returned at the next general election for Marlborough, eight miles west of his seat at Littlecote. He was on good terms with the corporation, who regularly sent him gifts of sack and wine, often after he reviewed the local trained bands.
In December 1620 Popham was nominated by Hertford for a seat at Great Bedwyn, a borough four miles south of Littlecote, and was duly returned.
Popham was involved in a contest against John Pym* for the junior seat at Chippenham in 1624. This resulted in a double return, which the privileges committee resolved in Popham’s favour, after a long delay, on 9 April.
Popham was re-elected at Chippenham to the first three Caroline parliaments. In 1625 he was appointed to the privileges’ committee (21 June), and to five bill committees, relating to the export of wool (27 June); Plumstead drainage (28 June); the estates of the 4th earl of Dorset (Sir Edward Sackville*, 8 July); sheriffs’ accounts (9 July); and rural depopulation (1 August).
In the 1626 Parliament Popham was appointed to the privileges’ committee (9 Feb.), and to consider bills concerned with administering oaths (11 Feb.); concealments (14 Feb.); ecclesiastical patronage (14 Feb.); and apparel (15 April).
Outside Parliament, Popham was involved in a number of contentious Chancery suits in defence of his property interests.
In the Long Parliament Popham represented Minehead, a seat which he probably owed to his connection with the Luttrells, and sided with the parliamentarians when civil war broke out.
