This family, known either as D'Arnay or D'Arnex, descends from Wibert, chevalier, living in 1109. The family settled at Orbe as early as the 14th Century.
Were there two Asperlin's near Aubonne in the 1630's? An Anthoine Asperlin with wife Salomé, and a Sebastien Asperlin with wife Salomé de Lavigny are mentioned about the same time in the baptismal registers at Yens. Besides Chatelain d'Aubonne, the title Sr. de Bavois is mentioned. Later records specify simply Sebastien.
He is apparently the Sébastien Asperlin, de Bavois, who was killed in a duel with Jaques François Olivier, as reported in an item in the papers of the Senarclens family (ACV P Château de Vufflens 597E, dated 09 dec 1651 or possibly 1657, a contemporary extract from the "manuel de la ville de Berne"—the date should be checked against records in Bern).
