Looking for Info About Hilea O Prince and His Ancestors from NY

I have been trying to find out if John Miller PRINCE is my grandfather's father. My grandfather's name was Hilea O. PRINCE born in 1883/84. I can't verify if John was Hilea's dad??? My dad's name was/is John William PRINCE born in 1910. As far as I know they were all born in NY state.

I have no idea if my grandfather had sibblings, I don't know who John M. PRINCE married...nothing. My father never talked much about his family.

PLEASE HELP!!
