While living at Reppe, France Vincent Voisin's occupation was listed as "laboureur" or "cultivateur" on the birth records of his children. He was a farmer or farm hand at that time. Sometime later the family moved to Felon, France, where he was a "meunier" or miller.

Felon may be derived from “foulon” or foulard, a lightweight plain-woven or twilled silk usually decorated with a printed pattern. The mill may therefore have been a textile mill rather than a grain mill. Maps show no river by it. Vincent may have worked at the mill along with his wife and daughter. They both died the same day at the mill. There could have been an accident, or perhaps both succumbed to an illness. Interestingly Vincent’s grandson, Alexander August Voisin, would become a tailor in Belfort, perhaps due to his grandfather’s involvement in the textile industry.

Anne Eve Denier's given name is written variously as "Aneve," "Anneve," "Annéve," and "Ann Eve" in multiple civil records for the births of her children. However she signed her name as "Anne Eve Denier" on her marriage record. I infer "Anne Eve" is the true spelling.

Jean Pierre Voisin was named in honor of his 1 year old brother, Jean Pierre Voisin, who died two months earlier.
