Their story
Caraunus, also called Caranus or Caro, was a native of Gaul. After his Christian parents died he gave all he had to the poor and retired into a desert, where the local bishop ordained him deacon. He preached in several provinces of Gaul and came to the country around Chartres, where few Christians remained from the converts of St. Potentianus and St. Altinus.
The faith spread through his preaching, and he set out for Paris with some disciples. Three leagues from Chartres he saw a gang of robbers approaching and told his disciples to hide in the thickets. Butler calls him a martyr. Butler and Baring-Gould agree on the fifth century.
