The New York Sun today reports the death of Diana Mosley, the wife of Sir Oswald Mosley, the hated British fascist. (The Sun reports that Diana Mosley never abjured her admiration of Hitler.)
In 1969 or 1970 I accompanied a person, a newspaper reporter, who interviewed Jessica Mitford in northern California. Jessica Mitford was one of Diana's sisters.
In the summer of 1961, in Columbus, Ohio, I met a tall British youth who called himself Alex Mosley and who claimed he was the son of Oswald Mosley. If the story was true, he was also the son of Diana Mosley. See British Boyhood: Alexander Mosley
It seems that in 1980 there was a publishing company in France called "Alexander Mosley Publications." My cursory internet research suggests the possibility that this publishing company published Diana Oswald's memoirs.
This is all very improbable.
Was the fellow in Columbus an impostor? But why would he have wanted to pretend to have such despicable parents? (The person who called himself "Alex" said that he had to leave Britain because he, "Alex," faced too many difficulties in Britain because his father was a notorious British fascist.)
