3-1-65 looking for Birthmom

My father was born on March 1st 1965, IN Fergus Falls MN. My father is looking for his family. He knows his father was an older man and that his birthmother was native American. His birth father was swedish. My fathers biggest wish in life is to know his biological family before it is to late. PLEASE email me if you have ANY information I can't think of a better birthday gift. Alexis@rock.com Thank You! Alexis
