Browne was almost certainly the ‘younger son’ in Denis Browne’s political dynasty who, during the Irish distress of 1822, was reported to have ‘scraped up £1,000 by hook and by crook’ and ‘laid it out in buying oatmeal’, which ‘he will now sell ... to the charitable for £4,000’.
In his maiden speech, 21 June 1831, he denied that the Grey government had failed to intervene to relieve Irish distress and defended the record of the Irish magistracy. He presented and endorsed Mayo petitions for additional Members to be given to Ireland that day and 13 July. He voted for the second reading of the reintroduced English reform bill, 6 July, at least twice against adjourning the debates, 12 July, and gave steady support to its details. He complained that anticipation of government relief for Irish distress had considerably diminished the charitable assistance of the British public, 6 July. He voted against disqualification of the Dublin election committee, 29 July, and the issue of a new writ, 8 Aug., and with ministers on the controversy, 23 Aug.; but he divided for printing the Waterford petition for disarming the Irish yeomanry, 11 Aug. He called for ‘more vigorous measures than any which have hitherto been acted upon’ to put down Irish disturbances, 15 Aug. He opposed further grants to the Kildare Place Society, 9 Sept. He voted for the third reading of the reform bill, 19 Sept., its passage, 21 Sept., the second reading of the Scottish bill, 23 Sept., and Lord Ebrington’s confidence motion, 10 Oct. He welcomed the appointment of a select committee on Irish tithes and called for a ‘radical reform in the church establishment’ to end the ‘hardship’ of Catholics having to support an alien religion, 15 Dec. He voted for the second reading of the revised reform bill, 17 Dec. 1831, again steadily supported its details, and divided for the third reading, 22 Mar. 1832. He complained of the ‘injustice’ of giving Mayo, with a population of 380,000, only two Members, 19 Jan. He voted with ministers on the Russian-Dutch loan, 26 Jan., 12, 16, 20 July, relations with Portugal, 9 Feb., and the navy civil departments bill, 6 Apr. He divided for the reception of the Woollen Grange petition for the abolition of Irish tithes, 16 Feb., but was one of the Members ‘usually opposing ministers’ on this issue who supported Crampton’s amendment regarding the payment of arrears, 9 Apr., when he explained, ‘I have been held up as an enemy to the people of Ireland, but I was sent here to maintain the authority of the law and the security of property’ and ‘will never court an ephemeral popularity which ... is too much sought after by some of the Irish representatives’.
At the 1832 general election Browne topped the poll for Mayo in a contest with two other Liberals. He lost his seat to another Liberal in 1835 and was defeated at a by-election the following year and again in 1847. He died at Plymouth, ‘aged 63’, in May 1862.
