RANA is our family assocation, Robidou Association of North America. We have a website www.robidou.org if you are interested in having a look.
I have to say, my own historical knowledge of Spain and the area Andre was from is lacking. So, we'll have to look into some of your questions.
As for Andre's father, it is believed he was a fisherman as well but we cannot say for sure. If you visit the website, we have a documented chronology of Andre's life from the time he boarded the ship in France to come to the New World (Canada).
