WILLIAM MORGAN, the third son of Sir William Morgan, who was Member of Parliament for Monmouth, 1628-9, became the ancestor of the branch at Rhymney. Sir William's only child by his second wife, Sir ANTHONY MORGAN (d. 1665) of Kilfigin was a prominent Royalist who fought at Edgehill. He was unable to compound for his property in May 1650, because he was a papist delinquent (see D.N.B.). Thomas Morgan was succeeded by his eldest son by his second wife, WILLIAM MORGAN (d. 1680). He was Member of Parliament for Monmouthshire in 1659-61. In 1661 he m. his first cousin, Blanche, daughter of William Morgan (d. 1649) of Y Dderw in Llys-wen, Brecknock, and Elizabeth, the youngest daughter by his first wife of Sir William Morgan. William Morgan, Blanche's father, known as the ‘judge,’ came from an Ystradfellte family and was the son of Morgan Llywelyn, gent. He was admitted to the Middle Temple in 1615. He was recorder of Brecon from 1637 till his death in 1649, the king's Attorney for South Wales, 1639-49, and Member of Parliament for Brecknock, 1640-49. He built up a lucrative practice at the Bar, which enabled him to purchase extensive estates in Brecknock. As his son, William, had d. in 1658, these estates passed with his daughter Blanche to her husband, and consequently gained for the house of Tredegar their dominant political influence in the county and borough of Brecknock. William Morgan was succeeded by his eldest son, THOMAS MORGAN (1664-1700), who d. without issue, the property passing to his brother, JOHN MORGAN (1670-1719/20), the fourth son of William Morgan. He was appointed custos rotulorum for Monmouthshire in 1700 and lord lieutenant of Brecknock and Monmouthshire in 1715. He was a strong supporter of the Whigs and represented Monmouthshire in parliament from 1701 till his death. On the death of his uncle, John Morgan, in 1715 he became lord of the manor and lordship of Gwynllwg. This John Morgan, known as ‘the merchant’, was the fourth son of Thomas Morgan of Machen and Tredegar by Elizabeth, his second wife. He amassed a large fortune in London and purchased Rhiwpera, where he retired to live. He was high sheriff of Monmouthshire in 1697 and Member of Parliament for the borough, 1701-5. In 1710 he purchased, for £9,000 the lordship and manor of Gwynllwg, which had to be sold by a decree of Chancery for the payment of the debts of the late earl of Pembroke. He made his nephew his heir. John Morgan was succeeded by his eldest son Sir WILLIAM MORGAN (1700-1731). He was Member of Parliament for Monmouthshire, 1722-31, and created a Knight of the Bath on the revival of that order in 1725. He was succeeded by his eldest son WILLIAM MORGAN (1725-1763) who was Member of Parliament for Monmouthshire from 1747 till his death. He was unmarried and, as his other brothers had predeceased him, the succession devolved upon his uncle, THOMAS MORGAM (1702-1769) of Rhiwpera, known as the ‘general.’ He was Member of Parliament for the borough of Brecon, 1723-34, for Monmouthshire, 1734-47, and for Brecknock, 1747-69. He held the office of Judge-Advocate General, 1741-68. He was succeeded by his eldest son, THOMAS MORGAN, the younger, of Rhiwpera (1727-1771), who was Member of Parliament for the borough of Brecon, 1754-63, and for Monmouthshire from 1763 till his death. He was unmarried and was succeeded in his estates by his brother, CHARLES MORGAN of Dderw (1736-1787), who was Member of Parliament for the borough of Brecon, 1763-69, and Brecknock, 1769 till his death. He was without issue and so was succeeded by his brother, JOHN MORGAN of Dderw (1741/2-1792). He was Member of Parliament for the borough of Brecon, 1769-71, and was returned for Monmouthshire in 1771, when the peace of the county was disturbed by the unusual event of a contested election, in which a ‘nabob,’ Valentine Morris of Piercefield, dared to challenge the supremacy of the house of Morgan. He suffered no further opposition and continued to represent the county till he d., 25 June 1792. On his death the male line became extinct and his elder sister, JANE, became the last heir of Tredegar. She was m. to Sir CHARLES GOULD(1726-1806), the elder son of king Gould of Westminster, the deputy judge advocate, who d. in 1756. Sir Charles Gould was appointed Judge-Advocate General in 1771, was made chancellor of Salisbury in 1772 and chamberlain of Brecknock, Radnor, and Glamorgan. He was Member of Parliament for the borough of Brecon, 1778-87, and represented the county from 1787 till his death. He was knighted in 1779 and made a baronet, 15 Nov. 1792. On the following day he assumed the surname and arms of Morgan (see D.N.B.). He was succeeded by his eldest son, Sir Charles MORGAN, bart. (1760-1846). He was Member of Parliament for the borough of Brecon, 1787-96, and for Monmouthshire, 1796-1831. In 1818 he unsuccessfully contested Brecknock against colonel Thomas Wood. He was famed for his liberality and did much to promote agriculture in Breconshire and Monmouthshire. Among his children by his first wife were CHARLES MORGAN ROBINSON MORGAN (1792-1875), the first baron Tredegar, CHARLES AUGUSTUS SAMUEL MORGAN (1800-1875), the rector of Machen and chancellor of Llandaff cathedral, and Charles Octavius Swinnerton Morgan (q.v.). C. M. R. Morgan was Member of Parliament for the borough of Brecon, 1812-18, 1830-2, and 1835-47. He succeeded his father as third bart., 5 Dec. 1846 and was raised to the peerage, 16 April 1859.

The two younger sons served in the Crimean War and the 2nd lord Tredegar, then a captain in the 17th Lancers, took part in the famous cavalry charge at Balaclava. He was Member of Parliament for Brecknock from 1858 till he succeeded to the title in 1875. He was created viscount TREDEGAR, 28 Dec. 1905.
