The October 17 1927 edition of the Toronto Daily Star contained this bit of what would now be called celebrity gossip, or perhaps royal gossip:
The Wikipedia page for Princess Ileana of Romania has no mention of her eloping at 18. She is listed as having married the Archduke Anton of Austria, Prince of Tuscany, which is at least a step or two up from an obscure naval lieutenant. The couple fled Romania during the rise of communism, eventually settling in the United States; they divorced in 1954.
Princess Ileana married and divorced again, and then became a monastic, taking the name of Mother Alexandra. She founded a monastery in the U.S., retiring in 1981 and passing away in 1991.
