Hi there my name is Teressa Louiseize(nee Dumbleton. My Grandmother's name was Thelma Decker before she married a John Dumbleton, I never got the chance to meet my grandfather as he died when my father Gary william Dumbleton was about 13yrs old.I was wandering if there was any Indian blood in the family anywhere, if there is from which side? My grandmother was born on January 6, 1919-died on February 17, 2001.I never had a chance to ask her any questions about the background, her death was a shock to the family.I was told that my grandfather had Cree indian in him, but I am stuck, because I don't know what his parents names where.His Name was John Dumbleton and he was born in or around 1899. He has another son named jack Dumbleton, that would have been born in or around 1947. My father Gary Dumbleton was born on December 13,1949. I hope you might be able to help me.
