Baron Dinevor, of Dinevor in the County of Carmarthenshire (usually spelt Dynevor), is a title in the Peerage of Great Britain. It was created in 1780 for William Talbot, 1st Earl Talbot and 2nd Baron Talbot, with remainder to his daughter Cecil, wife of George Rice, a member of a prominent Welsh family. On Lord Talbot's death the earldom became extinct because he left no sons to succeed to it, while the barony of Talbot was inherited by his nephew. The Barony of Dynevor passed according to the special remainder to his his daughter. The present holder of the barony is the half-brother of the Conservative politician Christopher Soames, Baron Soames. The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain after the Act of Union 1707 but before the Act of Union 1800. ... William Talbot, 1st Earl Talbot, Viscount Ingestre, 2nd Baron Talbot of Hensol (16 May 1710 - 27 April 1782) was an English nobleman. ... The Right Honourable Arthur Christopher John, Baron Soames, PC (October 12, 1920-September 16, 1987) was the last Governor of Rhodesia. ...
In 1916, the 7th BaronDynevor, Walter Fitz Uryan Rice, re-assumed the name of Rhys by Royal license for himself and his issue, but not before another street, this time in Betws, was built in 1906.
The Dynevors (whose surname is Rhys) claim their descent from the fifteenth century Rhys ap Thomas who had been granted extensive lands throughout west Wales as a reward for raising an army in support of Henry VII in 1485.
Her ladyship died on the 14th of March 1793, and was succeeded by her eldest son George Talbot Rice, the present BaronDynevor [in 1815].
