Hilliards in Indiana please read.

I'm new to the family tree searches but I'm interested in finding relatives.I've seen Hilliards from different states but none from Indiana.If there are any, I'd love to hear from you.I'm not really close to my father who is Charles R. Hilliard and his father was also Charles Hilliard.As you see I don't have much to go on doing this search.Any help would be greatly appreciated.
