Donna Douglas was born "Doris Smith" in Baywood, Louisiana, on September 26. She does not divulge her exact age. Unlike the other cast members, Douglas shared a great deal with her character Elly May. Like Elly, Douglas was a tomboy who grew up with a great respect for nature and animals. She spent her teen years cheerleading and winning beauty contests. She was named Miss New Orleans in 1957 and appeared as the Letters Girl on "The Perry Como Show" and a Billboard Girl on "The Steve Allen Show."

Douglas was extremely proud of The Beverly Hillbillies and her role as Elly May and is still known to do public appearances in her Hillbilly garb. She is also an accomplished gospel singer.
