My great-grandparents were Alexander and Rosalie Lauzon Dupell. The name Yette/Yette sounds familiar to me, though I don'tremember having a great-aunt Mary. That I know of, Alexander and Rosalie had 4 daughters -- Louise, Florence (Flossie), Bernadette and Victoria. Was there a 5th? There were at least 6 boys that I can recall - Eli, Patrick, George, Ernest (Jack), Thomas and Joseph. Do you have more information on this side of your family?
Thanks, Gisele Dupell Freed
