Jehan Vuilloz (or Vuille), who owned land in La Sagne in 1436, was the father of Jeannin Vuille, mayor of the village of La Sagne in 1495. Jeannin had a son Henry, and our line passes from him to his son Jehan, grandson Henry, and great-grandson Guillaume. Little is known about these early members of the family except their names, recorded as land and rights passed from father to son. The names of their wives are never mentioned.
Guillaume had a son David Vuille, who married Susanne Comtesse in the early 1600s - the first recorded female ancestor in this line. Their son Jean was a parish counsellor at La Sagne, and married Bendichte Grandguillaume-Perrenoud. Jean and Bendichte had at least two sons, including Abraham Vuille, who married Marie Vuille (daughter of Isaac) at La Sagne on 13 December 1699.
Abraham and Marie's son Jean-Louis Vuille was christened at La Sagne on 10 June 1703 and married Susanne Matile there on 26 February 1743. He was the last child recorded at La Sagne with four godparents: below his entry in the baptismal register, the pastor added a note that henceforth it was no longer possible to have more than one godfather and godmother, and that extravagant baptism feasts were strictly forbidden!
Jean-Louis and Susanne had twelve children, all born in La Sagne. Their fourth child, David-Louis Vuille, was born on 7 September 1740, and married Marianne Vuille in La Sagne on 25 September 1804. (Marianne's line is shown below.) They had three children, including Julie Vuille, who was born in La Sagne on 30 October 1811, and married Gustave Perrenoud there on 6 August 1831.
