Charles Thomas Livingston OR Daniel Charles Livingston

I have found information in census that says my ggrandfather was Daniel Livingston; but everyone called him charles. My grandmother had his info listed as Charles thomas.

Could there be that much of a coincidence if census that there are two men who were born in same year and married wife of same name in same year with their first born having the same name?

Charles or Daniel Livingston married Minnie Stacy their first born was madge? Anybody else have info like this?
