Ah didn't see that about the French guy. The article isn't very explicit about this point, though if you look at the totals by nationality, there are 105 hostages (all Jews) and of them 92 are Israeli. Also, if your mother converted to Judaism before you were born, you're 100% Jewish. The only potential sticking point would be if she was converted under Orthodox law. I am not familiar with the Rabbinate's position on that, but 99% of the Jewish world recognizes you as a Jew. Your case is quite strong as a matter of fact.
