Origin of the word Chevrolet as a (last name : surname)?
Not this:

"chevalier, a nickname for "knight." Chevalier comes from cheval, the French word for "horse""?


Most likely, this:

"Chevrier (one who took care of goats)"?

"Some place names are a little cryptic, such as Chevrolet, the French place name that means "little goat ." The name referred to the picture painted on the outdoor sign at a roadside inn. Pictures were used since few had reading skills, and in that era [14th century], chevrolet referred to a place."?

But, the Chevrier Family Crest (does not look like a bow tie)
