I saw your your post 2/13/2013 and realized I had correspondence with your dad(?)many yrs ago.
Found the following in my saved file.. Probably won't help your search, but may have sentimental value.

DEAR GENE I TRIED TO CONTACT YOU BEFORE,BUT I COULDN'T GET THROUGH WITH THE E MAIL ADDRESS THAT I HAD. WE HAD SOME HEALTH PROBLEMS SO WE NEVER GOT TO GO TO PARIS.
I AM GLAD THAT I HAVE YOUR E MAIL ADDRESS NOW .
I DO NOT KNOW WHEN WE WILL GO TO PARIS BUT IT WAS GOOD TO HERE FROM YOU.
BOB NONNON "
At that time we concluded that we "Nonnon's" were probably from a different family line. At that time I had concluded that my g.g. grandfather, Eugene Nonnon, came from the Ardens area of northern France, abt. 1855-1860. But now it seems possible that he was from Caan, western France. The given names of his brothers,were Ernest and / or Auguste.
