Which character had a twin on the U.S. TV show "The Beverly Hillbillies"?

The character who had a twin on the 1962 - 1971 U.S. TV show "The Beverly Hillbillies" was Jethro Bodine (Max Baer). Jethro had a twin sister. They are fraternal twins.

Jethrine Bodine was voiced by Linda Kaye Henning in 11 episodes in season one. Jethrine is Pearl's king-sized daughter; it is clear that she isn’t identical to Jethro. Jethrine appears in the first season; she moves with her mother to the Clampett mansion later that season, but occasionally is not seen in episodes during her stay in California.

Jethrine is upset to leave the hills, as it means separation from her "sweetie", traveling salesman Jasper "Jazzbo" Depew (played by Phil Gordon in episodes in the first series). Late in the season, an episode explains that Jethrine returns home to marry Depew.

Jethro and Jethrine rarely appear in the same scene in any of the episodes, and then they are never on-camera at the same time, except for the rare back-of-the-head shot using a double. In 1993, Jethrine appears in the movie version of "The Beverly Hillbillies".
