In his early twenties Carew was thrice returned for Haslemere with his even younger cousin Poynings More as junior colleague, thanks to the influence of his maternal grandfather Sir George More, who owned the lordship of manor in which the borough was situated.
Two years later Carew and Poynings More were returned together for Guildford. However, a second, rival indenture named Robert Parkhurst rather than Carew alongside More. Carew played no recorded part in the 1628 Parliament and it is Parkhurst’s name which appears in the Crown Office list. This may indicate that it was the latter who took the seat, but there is no evidence of an adjudication by the Commons.
to be wary of your living there, and to live as privately as you can, yea though it were to the changing of your name and the cutting off your long hair, to alter your favour; also to be very wary how you accompany yourself with any priests or Jesuits or any fugitives.
Carew accepted the spiritual advice, assuring his father that he would ‘avoid the crafts and subtleties either of Jesuits or devils’, but wrote to his wife to send him a trunk full of expensive clothes, some of which she would have to buy. This request was too much to bear for the elder Carew, who complained to his son that it was ‘as though all Paris and France had not sufficient to furnish your proud and vain mind’. At the end of the year he wrote that nothing could be done about his son’s debts: his mother-in-law Lady Romney would not pay them, and his own lands were encumbered with jointures and entails. ‘I am very sorry I never could nor I think never shall know the certainty of your debts’. Carew was still in France in the summer of 1631, writing now to his father in French, but the birth of his son in June 1635 suggests that he must have returned home before the winter of 1634.
Carew contested Bletchingley in the spring of 1640, leading to a double return, but was never allowed to sit in the Short Parliament.
