Like all of you I am looking for my roots. However I am in British Columbia, and there happens to be a Deroche, BC if anyone is interested.
I am a Desendant of Simon Peter DeRoche(my grandfather) he had one brother that I know of, Joseph Armand DeRoche. They were both located in the north cowichan district of vancouver island. I do know that they relocated before that to northern vancouver island from Campbellton, New Brunswick. This sadly is where my knowledge ends.
