If your grandfather's sister is his aunt, I'll assume that your aunt married his uncle. If so, then he's not a blood relative...so I'm not sure what that would make him. If he IS a blood relative, then your grandfather would be his uncle, making him your mother or father's cousin and therefore your first cousin once removed.
I think the best you can do is first cousin (once removed) via marriage
