|Médard Chouart's baptism record |
I downloaded the record (above) a few years ago, but could only partially decipher the Latin text:
31 […] [die?] […] [x. […] [baptizatur?] [fuii?] Medardus filius Medar / Souar de Mariae Poirier [coningmy?] [C---iraxman?] fui Ant[onius / Chouar maxenna aubry Fllim […]
Basically, the words translate into English as Medar, son of Medar Chouar and Marie Poirier, was baptised on 31 July1618. The godfather was Antoine Chouart, presumably brother to the elder Médard. 
The officiating priest of St-Martin, a 12th century church, did not indicate when Médard was born, but it’s reasonable to think that he received the Sacrament the day he was born or the next day.
Few details are known about Médard’s early years due to the “obscurity that covers his youth”.
