[12] His second son, Godfrey Morgan fought in the Charge of the Light Brigade in the Crimean War[13][14] and was made Viscount Tredegar in 1905.

[20] In the early 1930s, Morgan was engaged in writing a novel based on his time living as an expatriate in New Zealand and Australia, before returning to London in 1932.

[23][24] During the Second World War, Morgan served in Scotland and the Middle East, gaining the rank of officer in the King's Own Scottish Borderers.

[26][27][28] In 1950, he was promoted as an Officer of The Order of St John, having already been Assistant Almoner for the Priory of Wales for sometime, and elected as an honorary member of the Newport Chamber of Trade.

[31] Evan spent copiously during his life with a menagerie of bears, birds, and kangeroos installed at the family home, while his weekend house parties played host to the likes of H.G Wells and Aldous Huxley.

[2] Frederic, who described himself as an "arthritis cripple"[33] decided to immediately transfer the entire Welsh estate to his son, John, to avoid the payment of a second set of death-duties on his own demise.

[33][34] At the time, Morgan told the Western Mail that he was prepared to "live at Tredegar Park on a very modest scale in view of the prevailing conditions" adding "although my father is crippled with osteo-arthritis, it is my earnest wish that he may be enabled to share with me the family home where he spent so many happy years of his early youth.

John Morgan bought the majority of the "non-heirlooms" from his cousin's executors, including the contents of Honeywood House[e], for which he paid £8,837[f], having been valued by Sotheby's.

[37] In his father's final years, Morgan had already begun selling off parts of the once 88,000 acre estate in an attempt to recover the family's lost fortune.

[38] Later, Morgan directed Stephenson & Alexander, a firm of auctioneers, to dispose of the remaining contents of the house in sales on 11-12 July 1951.

[43] However, Morgan allegedly severed all family links to South Wales in 1953, after he failed to receive an invitation to meet Queen Elizabeth II and the Duke of Edinburgh during a royal trip to Newport.

[47] In his book, Midway on The Waves, James Lees-Milne describes a journey with Morgan to Ruperra, shortly after the Second World War.

He wrote, "the Welsh want to buy the castle from John as a memorial to Welshmen killed in the war and vest in the National Trust", adding "I could not see any point in it at all".

[47] In February 1956, it was reported that the 53,000 acre Tredegar agricultural estate was to be sold in a series of auctions overseen by Lane, Saville & Co.

[51] In November 1956, it was revealed that a 72-year-old woman living in Roath, Cardiff, had been asked by Morgan's agents to pay £515 for her house, despite similar properties having been sold for £100 two months earlier.

[52] Cliffe stated that he had "written to Lord Tredegar, but received no response", and that he was "shook" by the incident, having "consistently referred to Morgan's generosity throughout the union's meetings".

[52] Morgan's solicitors wrote to Cliffe explaining that "the sale of the freehold was completed some time ago, and it was not possible to re-open negations".

[66] Despite liquidating his Welsh estates and property in lieu of death-duties, Morgan claimed that further taxation forced his decision to emigrate to Monte-Carlo, Monaco, as a tax exile.

[67][68] In Monaco, he pursued his interest in art, having studied under Leonard Fuller at St Ives School, and produced several works which are now owned by the National Trust and displayed in Tredegar House.

[76] Morgan also specified for his funeral to be carried out in the "simplest manner", wishing for any money that would have been spent on flowers to be donated to the Catholic Church or charity.
