English: Coat of arms of the Viscount Portman: Portman quartering Berkeley of Pylle, Somerset (a junior branch of Berkeley of Bruton Abbey in Somerset). The Manor of Pylle became a possession of the Berkeley family of Bruton Abbey in Somerset, a junior branch of Berkeley of Berkeley Castle in Gloucestershire. It was the paternal inheritance received by Sir Edward Berkeley (1580-1654), the third son of Sir Henry Berkeley (1541-1601) of Bruton. His grandson Edward Berkeley (c.1644-1707), of Pylle, served three times as a Member of Parliament for Wells in Somerset. William Berkeley (d.1737) of Pylle changed his surname to Portman on becoming heir to his distant cousin Sir William Portman, 6th Baronet (d.1690) of Orchard Portman in Somerset. His descendant was Edward Berkeley Portman, 1st Viscount Portman (1799-1888).
