Okay thanks guys. But I think you have misinterpreted my question. My husbands father was french, grandparents were french. My husband is English, born in UK. We have all the french birth certificates, passports, war record for my father in law (with the free french airforce, including a medal), and documents for grandparents. My husband want to apply for french citizenship ( dual nationality). This is the info I need and with respect it does not seem to appear in the website that people are referring me to. Or perhaps someone could copy and paste it because I really cannot see the actual relevant info I need. Anyway, thanks all for your attempted help, the search will continue. This is why I am hoping that someone who has been through the process can point me in the right direction.
