Dates of existence
The Morgan family claimed descent from Bledri (d. 1120), the third son of Cadifor Fawr (d. 1089), lord of Cilsant, now in Carmarthenshire. Sixth in line of descent from Bledri was Llywelyn ab Ifor, lord of St Clears and Gwynfe, who married Angharad, daughter and heir of Sir Morgan ap Maredydd, and in her right acquired the estates of Tredegar and Cyfoeth Feredydd in what is now Monmouthshire. His son Morgan (d. 1375x1387) succeeded to Tredegar and St Clears, and Tredegar descended within the Morgan family for almost six centuries. The second son of Sir John Morgan ('Y marchog tew', d. c.1492) was Thomas, an esquire of the king's body (21 Hen. VII), and ancestor of the Morgan family of Machen, which later became the senior branch of the family.
In 1661 William Morgan (d. 1680) of Tredegar married as his first wife Blanche daughter of William Morgan of Dderw in Breconshire, by which marriage that estate came to the Morgan family of Tredegar. He also married (2nd) Elizabeth, widow of Sir Francis Dayrell (d. 1675) of Buckinghamshire, and daughter and coheir of Edward Lewis of the Van, Glamorgan.
The male line of the Morgan family of Tredegar failed with the death without issue of John Morgan (1742-1792), and he was succeeded by his eldest sister and coheir Jane, wife (m. 1758) of Sir Charles Gould (1726-1806). In 1792 Gould was created baronet and changed his surname to Morgan. His grandson Sir Charles Morgan Robinson Morgan (1792-1875), 3rd baronet, was created Baron Tredegar in 1859. His second, but eldest surviving, son Godfrey Charles Morgan (1830-1913), 2nd baron, was created Viscount Tredegar in 1905, but he died unmarried, when the viscouncy became extinct. The barony devolved on his nephew Courtenay Charles Evan Morgan (1867-1934), 3rd baron, the eldest son of Frederick Courtenay Morgan (1834-1909) of Ruperra Castle, the third son of the 1st baron. This 3rd baron was created Viscount Tredegar (2nd creation) in 1926, and was succeeded by his only son Evan Frederick Morgan (1893-1949), 2nd viscount. The viscouncy became extinct on his death, but the barony and baronetcy devolved on his uncle Frederick George Morgan (b. 1873), 5th baron and 7th baronet, the second son of Frederick Courtenay Morgan (1834-1909).
The 5th baron was succeeded by his only son (Frederick Charles) John Morgan (1908-1962), 6th baron, who died childless. The barony became extinct on his death.
