Caruana declined being ordained a
priest to marry Maria Metropoli, one of three daughters of Giuseppe Metropoli, notary to the
Roman Curia in Malta, whose two other daughters married the 6th Count Preziosi and Salvatore dei Duchi Mattei. Their only son,
John Caruana, was a 20th-century Maltese philosopher and constitutional lawyer and the son-in-law of the Victorian architect
Emanuele Luigi Galizia. One of Caruana's direct descendants married the Maltese investigative journalist
Daphne Caruana Galizia, who wrote a thesis on his life and work for her degree in archaeology at the University of Malta. Caruana lived at 266, St Paul's Street, Valletta. ==References==
