If you are going to play any French songs on guitar at a cabin it has to be Harmonium.
Harmonium is (was?) an awesome Quebecois folk band from the 70's. Everybody knows them. Your family will recognize "Pour un Instant" and many others in seconds.
Any folk fan french or not would really like them.
Here is their site:

I could not find any music samples aside from some crap midi files on Harmoniums site.
