Sharon, I had hoped this Perrot book would help those interested..I feel rewarded. Some interpretations of "Metaminems" was "Iron legs".I have been to the Neville Museum in Green Bay and saw the Nicolas Perrot gift Monstrance that is on display. They don't have much more data on him.Have you tracked your grandmother's ancestry with Robert Perreault's records? I'm also from Minnesota!! I've also read of Henry Schoocraft's expeditions.
