I am doing research. I have no information on my biological paternal grandmother. According to my dad's birth certificate, she was born about 1890 in Montana, USA. spouse was Albert LaValley b. abt 1894 in Montana d. abt 1930 in Chinook, MT.Albert LaValley was French Metis(Chippewa/French)who descended from Canada(maybe Manitoba). The Dustin/Dustan's are a mystery.I have an abundance of information on the LaValley's, but nothing on the Dustins.
