Perrot was raised in a provincial Breton-speaking family. After studying at the Institut des Frères des Écoles in Guingamp in 1889, he expressed a desire to become a priest.

In 1920, he was named vicar of Plouguerneau. In 1922 Yves Floc'h, the future painter worked as his parson. Perrot patronised Michel Le Noblez and organised theatrical performances.
