Penleaze’s ancestry and origins remain obscure, though it is possible that his grandfather was James Penleaze, the Middlesex magistrate who died in Church Street, Spitalfields, 9 Sept. 1783.
Penleaze was elected a burgess of Southampton, 8 Sept. 1826, and became deputy bailiff and a member of the borough council, 30 Sept. 1828, by which time he had presumably acquired his residence in the town.
Penleaze did not redeem his pledge to try again at the 1830 general election, by when he had resigned his burgess-ship, stating his intention to move away.
A jaundiced commentator on his earlier attempt to enter the Commons had predicted that ‘if he could not speak better in the House that he does out of it [he] would ... add another name to the glorious 658 who on all occasions confine themselves to the scriptural text of Aye and Nay’.
He voted for the second reading of the revised reform bill, 17 Dec. 1831, and again gave steady support to its details. On 2 Feb. he presented a Southampton petition for a general drainage system, which he endorsed, presciently enough, with reference to the cholera epidemic, and called for a survey of ‘the abodes of the poorer classes ... to see that their health is preserved by a due attention to cleanliness’. He divided for the third reading of the reform bill, 22 Mar., and the address calling on the king to appoint only ministers who would carry it unimpaired, 10 May. His steady conduct was praised in his absence at a Southampton meeting, 14 May.
At the 1832 general election he offered again for Southampton, boasting of a peerless record of Commons attendance, though he was obliged to admit that he had compromised his views in support of the ballot.
