Morgan, an anti-Catholic Tory, had been brought in for Brecon by his father in 1818, when his elder brother Charles stood unsuccessfully for Breconshire. He had supported Lord Liverpool’s administration with Sir Charles, but spoke against the proposed equalization of the coal duties that threatened their vested interests in the Monmouthshire borough of Newport. His brother choosing to remain out of Parliament, he came in again for Brecon in 1820 at a cost of £388 9s.
Morgan did not stand for Parliament again. In August 1845 he died intestate at Brickendonbury, where he had planted a magnificent avenue of trees known as ‘Morgan’s Walk’. He was buried in the Clarke family vault at All Saints, Hertford. Administration of his personal estate, sworn under £5,000, was granted to his widow, who in 1855 married Captain Claridge, the promoter of hydrotherapy. His nephew the 2nd Baron Tredegar sold Brickendonbury in lots between 1878 and 1883.
