well hello dont know these individuals currently, will look them up. am just learning the ropes of geneological research and am new to computers...but I can share lots about other dumont individuals of pentwater, my late father,F. Wm. DuMont was vice pres. of pentwater historical society, a charter member in fact. I have all of his research and my own. my great, great grandfather was Noah DuMont born 1847, Mich. Spent all my summers as a child running wild and swimming in beautiful old pentwater and am descended from danish pioneers there as well.
