After spending his youth in study, he entered, in his twenty-fourth year, the friary of the Third Order Regular of St. Francis, founded in Picpus-—now part of Paris—-by his uncle, Jérôme Hélyot, a canon regular of the Order of the Holy Sepulcher.
The French congregation, named from their house at Paris "of Picpus", was reformed by V. Mussart (d. 1637), and maintained close ties with the First Order till its extinction in the French Revolution.
