Mrs. Batman and the Parkers
Jean Parker (no relation) ran a Palm Springs airport in the 1940s and married Batman. Before playing Batman or marrying Jean, actor Robert Lowery appeared in a Jimmy Cagney movie called Great Guy (1936) as a character named "Mr. Parker," who is no relation to Jean Parker or C. Parker. None of us are related to jazz man Charlie Parker, who played alto saxophone and was not a gunslinger. Gregory Peck played a gunslinger in The Gunfighter (1950), and Jean Parker was in that movie, too. Which is really neither here nor there.
