Vincent was born in 1581 in the village of Pouy in Gascony, in the Province of Guyenne and Gascony, the Kingdom of France, to peasant farmers, father Jean and mother Bertrande de Moras de Paul.
Vincent's interest in the priesthood at that time was largely with the intent to establish a successful career and obtain a benefice, with which he could retire early and support the family [REF].
