Thanks for your suggestion. Where do you live? I've never heard of International Coupon Responses. And, I wouldn't know where to get them. I'd appreciate any insight you might have on that.
I don't read French but I'm pretty resourceful when it comes to things like that. I'd be open to any genealogy site that you'd like to share with me.
Unfortunately, I 'm not familiar with any of the surnames that you are searching for. And, I'm not certain if LDS has any data for Corsica, but maybe you could check with their website if you haven't already done that. If you need their web address, just let me know and I'll send it to you. Good luck!
