Maturo

This name derives from the Latin “mātūrus”, meaning “mature, ripe, adult”, from “mānĕ > mātūtīnus (morning, early riser), from the same Latin root “mā > mētĭor > mētīri” (time, measure), which in turn derives from the Ancient Greek “métro (μέτρο) métron (μέτρον)”, meaning (measure). The name does not derive from the Celtic word “matu” which means “good.” Saint Maturinus or Mathurin († ~300 AD) was a French exorcist and missionary venerated as a saint. The first source to mention Maturinus is the Martyrology of Usuard, written in 875. In the next century, a biography of Maturinus was composed. The feast day is traditionally celebrated on November 1.
