Except there are two characters introduced in the first issue. Flash Comics #1 (Jan. 1940) One is The Whip, the other is the original El Castigo, who he takes his persona from. El Castigo actually means more like punishment(er), yet I can see how they took it to mean to whip. So "the Whip" is the "contemporary" Rodney Gaynor caucasian legacy character's name, who they later retconned as being Hispanic himself. As Rodrigo / "Rodney". But the original character he takes his theme from, is Fernando Suarez El Castigo who (as offensive/cliche) he is definitely meant to be Hispanic. .
