I got a little tidbit!

So... I was wondering why they would refer to their grandma as "my queen" since I thought that was a bit strange. I searched my brain for what else "maraine" could mean and then I realized it could have possibly derived from "mère" (meaning mother in french) and "aîné" (meaning elder in french). thus, "maraine" would mean "elder mother" which I think makes more sense than my queen. Even more so because they are singing "my maraine" which would be like saying "my my queen"??
although... I could be completely wrong.
