John Morgan, 6th Baron Tredegar

Frederic Charles John Morgan, 6th Baron Tredegar, OstJ, RYS, (26 October 1908 — 17 November 1962), styled the Honourable John Morgan between 1949 and 1954, was a Welsh peer and landowner. His forebears' lavish spending and disagreement regarding estate planning meant that on his father's succession to the Morgan titles and estates in 1949 their future was uncertain, and £1,000,000 was to be paid in inheritance tax. Although efforts were made to protect the longevity of the estates, the burden of death-duties was too great, forcing Morgan to liquidate the entirety of the family’s estates. John Morgan's death in 1962 saw failure of the male Morgan bloodline, and the extinction of the Morgan titles, bringing an end to a social and political dynasty that had dominated South East Wales for 500 years.
