By "family" I meant Cousteau's family during the war, not all his descendants of course. Sorry if that was unclear.
But he was a Nazi sympathizer and was protected by the Germans during the war. Then he falsely claimed to have been a member of the Resistance. This is all documented in his biography.
Once more, I have to ask you, if you do not mean to implicate Cousteau's entire family, all the way up to his great-great grandchildren, for Cousteau's antisemitism, then why are you bringing his antisemitism up in a discussion about his grandson?
Why is what you are doing here any different than reminding everyone of Adolf Hitler and the Nazis everytime someone talks about modern Germany, or Angela Merkel?
