Today is the 85th anniversary of the engagement of Princess Ileana of Roumania and Count Alexander "Lexel" of Hochberg. It was a short engagement, and the wedding called off, after Marie took her daughter to Egypt, telling her that Lexel was gay.
Lexel's mother was the British-born Princess Daisy of Pless (Mary Theresa Cornwallis-West.)
Here is a selection of books about Daisy and her family. There is a book about Lexel, entitled The Three of Us by Laurence James Ludovici, published by Marjay Books. I have a copy in my personal library, but the book does not appear on Amazon. Give addall.com a try.
