Jean Ducas dit Labreche b. approx 2 Jan 1657 Oloron, St. Pierre, Bearn France.Son of Jean or Pierre Ducas (Ducha) and Marie Deshayes, Marie Bos or Catherine de Pereuil.
The ambiguity about the mother of Jean Ducas stems from the fact he used 2 different names for his mother on his marriage records (church and notary) and a likely birth record found in Oloron for him listed a 3rd name.
