I can't understand why Roger would be looking for Catholics in Cananda when in France the mystery surrounds groups of people who were enemies of Rome...the Cathars, the Waldensians..the entire south of France was known as a hot bed of heretics. People who just would not give up their old religions for the Universal Church/Government.
So why are you looking for Catholics in Canada?
And why Canada? The Huguenots ended up all over the world...including South Africa where a huge monument has been erected in memory of them. The exiled French went to colonies in Florida, Massachusettes, Virginia, South Carolina and Georgia. They named an island in Nova Scotia "Oak Island" and one in North Carolina by the same name (as above/north, so below/south).
Many of the families that left France were prominent people. http://huguenotsocietyofamerica.org/?page=Huguenot-History
The Huguenots were French Protestants. The tide of the Reformation reached France early in the sixteenth century and was part of the religious and political fomentation of the times. It was quickly embraced by members of the nobility, by the intellectual elite, and by professionals in trades, medicine, and crafts. It was a respectable movement involving the most responsible and accomplished people of France. It signified their desire for greater freedom religiously and politically. [b]The names of Huguenot leaders at that time included the royal houses of Navarre, Valois, and Condé; Admiral Coligny, and hundreds of other officers in the military.[/b] Marguerite d'Angoulême (pictured right), whom scholars have called "the first modern woman," was an early supporter of reform in the Catholic Church. She influenced her brother, Francis I, to be lenient with the Huguenots.
As Esther Forbes, wrote in Paul Revere and the World He Lived In
(Boston: Houghton Mifflin Company, 1942):
France had opened her own veins and spilt her best blood when she drained herself of her Huguenots, and everywhere, in every country that would receive them, this amazing strain acted as a yeast.
They acted like royalty because the were royalty. They married into the same families they had always married into....other royalty. Especially the royalty that had just been kicked out of Scotland...bonnie prince charlie's family...the Jacobites.
If you read their letters and books you will see that they communicated with other family members in other Huguenot areas...the De Veaux's had family members in Georgia, South Carolina and Nova Scotia...they were hedging their bets.
