In November 1614 Pryce was admitted a student of the
Inner Temple. Initially a
Royalist, in 1628 he was created a Baronet. In October 1640, at the outset of the
Long Parliament, he was elected to the
House of Commons from
Montgomeryshire. On 12 October 1642, together with his fellow-member
Richard Herbert he was disabled from sitting in parliament, on account of their having joined the
king at
Oxford in the initial stages of the
English Civil War. In 1644, though, he changed sides and was appointed Parliament's Governor of
Montgomery Castle. In the
First Protectorate Parliament of 1654–1655, he returned to the Commons, again as a member for Montgomeryshire. ==Marriage and children==
