Scruffy, the name Nasbinals is a corruption of the languedocien, Las Binals. I think the sounds just got scrambled, much as the River Olt is the River Lot in French. I think.
My Provencal dictionary gives no clue as to the meaning, which is not surprising. The old languedocien language - a part of Occitan group - had a guyennais or northern dialect. Within that dialect area, there was a variant, gévaudanais, spoken around Nasbinals. I think.
As to symbols, that interesting auvergnat church was a priory of the order of Saint-Victor de Marseille. Is there some connection between that and the heraldry?
Whew!
I stayed at the equestrian farm, and the weather was so severe there was no question of a stroll into town. But I loved all that high country, even in the most hostile conditions.
Your interest and anticipation are getting me quite inspired.
