The Lane Sisters, a singing/acting trio famous during the ’30s and ’40s, actually began as the Mullican sisters. And there were 5 of them, not 3.
The Mullican family of Iowa consisted of parents Lorenzo and Cora and daughters Leotabel (nn Leota), Martha, Dorothy (nn Lola), Rosemary and Priscilla.
Four out of the five daughters pursued careers in entertainment, and three out of the four saw success in film. Along the way they changed their surname to “Lane,” so the final three — Priscilla, Rosemary and Lola — became known as the Lane Sisters.
P.S. Remember that post about Torchy Blane? Lola Lane, one of the actresses who played Torchy, inspired Superman co-creator Jerry Siegel to create the character Lois Lane.
