I have an interest in the French protestants known as the Huguenots. My family (on the Bedard side) are originally from La Rochelle, one of the Huguenots strongholds in France.
While the Bedards were all Roman Catholic by the time they arrived in Canada, I suspect some were Huguenots. It was common for Huguenots to convert to Roman Catholicism after the St Bartholomew’s Massacre in 1572.
Here is a helpful documentary by Ryan Reeves. I have shared other of his videos and they are very good.
