The Bernard Family was from the small town of Réchésy, located in eastern France right on the border with Switzerland. According to his children's birth records, Leon worked as a shoemaker (cordonnier) in the village.
I clipped a few screenshots of the streets of Réchésy from Google StreetView. The streets appear quite hilly, which is to be expected in the foothills of the Alps. There is also a distinctive Alsace architectural look to some of the buildings, which makes the village very picturesque indeed. (Click on images for larger view.)
