Sie hatten offenbar zwei Söhne:
www.filmspot.com:
„John was married to actress Gena Rowlands from 1954 until his death on 3 February 1989. They had four children, Nick, Alexandra, Zoe, and Frank Cassavetes.“
Auch auf imdb.com ist von 4 Kindern die Rede; insofern scheint die Information vertrauenswürdig.
Viele Grüße
Karl
