CARROLL aka RUFIANGE
While digging into my mom's French Canadian line, I came across my Carrolls in Canada. Although they used CARROLL (and variations) here in the US, they were RUFIANGE dit LaViolette in Quebec.
Although I knew the French did this, it still blew my mind and nearly gave me a genealogical melt down!
I hope this helps someone.
