Bampfield belonged to a cadet branch of the prominent Devon gentry family headed during this period by his distant cousin, John*.
In 1614 Bampfield was returned to the Commons for Bridport, doubtless through Trenchard’s local influence. However, he was simultaneously pursuing a Chancery suit against Sir John Wentworth*, and, between the issuing of the parliamentary writ for Bridport and the actual election, he was committed to the Fleet for contempt of court by lord chancellor Ellesmere (Thomas Egerton†). Trenchard’s son-in-law, Sir John Strangways*, claimed privilege for Bampfield on 9 Apr., and the Commons ordered his release five days later. Brought into the House by the warden of the Fleet on 16 Apr., Bampfield took his seat, but played no known part in the Parliament’s subsequent proceedings.
In 1618 Bampfield was indirectly involved in one of the great scandals of the Jacobean Court, when his wife gave evidence on behalf of the countess of Exeter in the latter’s defamation suit against the family of Sir Thomas Lake I*. A year later, he leased part of Drury House, Westminster from Christopher Brooke*.
