It does sound like it could be French.
Unfortunately I know nothing about French bikes but I would suggest searching for Peugeot's, etc, and see if you can find a frame that looks like yours.
Personally, a nice paint job and a clean up, replacement of worn parts, upgrade to better quality components would be my suggestion. I would also suggest to keep the French character of the bike.
Best of luck,
Gary.
