Looking for Relatives to Grandfather John Charles Dyke

I am looking for any relatives for my grandfather (John Charles DYKE) I only know this name because i have the same name. My father was Ronald John DYKE. i also do not know my grandmother's name, through the years i have ran across 2 DYKEs (one was in Dillon, CO.- William DYKE and the other was at a snowmobile rental place that was in Frisco, CO-Steve DYKE). I amd hoping that i have more family than just my brother James P. DYKE.
