OLSON FAMILY - NEW YORK - NEW JERSEY AREA

I am searching for my Norwegian roots. I know it may be impossible as I have hardly a chicken egg to start with. I only know that my grandmothers name was Olga (Sophia?) Olson, born October 7, 1901, not sure where and she died August 1972 in Glens Falls, New York-USA and that one of her brother's names was Magnus, and another was Edward who lived in Glendale, New York and she married Fritz (Frederick J) Neumann in Glendale?(not sure of city) New York-USA. Any help you can give will be greatly appreciated.
