Pryse was heir, through his mother, to an estate of 30,000 acres in upland Cardiganshire.
In Parliament Pryse had nothing to say in debate, but voted frequently with opposition, beginning with the Windsor establishment bill, 22 Feb. 1819. He supported Tierney’s censure motion on 18 May, the repeal of the coal duties, 22 May, and voted against the foreign enlistment bill, 3, 10, 21 June, and the malt duty, 9 June. He did not appear in the minority lists in the ensuing session. He continued to be ‘a supporter of the Whig party’. He died 4 Jan. 1849.
