Looking for My Kingsley Family

I am doing research on my Kingsley family. I am Rene M Kingsley, b.1961, Minneapolis, Minnesota. My parents are Arthur James Kingsley, b. 1938, Riverside, California, d. 2006, Mesa, Arizona, and Beryl Joanne Kinkel, b. 1935, Minneapolis, Minnesota.

Grandfather: Harry James Kingsley b. 1906, Wisconsin
Grandmother: Florence Ethel Kay Kingsbury, b. 1914, California

I am trying to find out who Harry's father and mother were and so on..

Any one with any information, please feel free to message me. Thank you in advance.
