Hi
Unfortunately France did not have a centralised registration system. You will need to find out where your village is + then write in French to the Town
Hall enclosing a stamped addressed envelope (there is a template on the internet for this if you put in a search). When friends go to France on vacation they bring me back French stamps so I can do this. Or you can find a French group on rootsweb or yahoo - there are heaps of them. It seems a bit daunting but with no centralisation of registration + not many departements (counties) on line it's not an easy job. Make a friend on a French site!
