When researching this, I was surprised to find that Jethro is the sole living member of the Beverly Hillbillies original cast.

There are four biblical names associated with Jethro; Hobab and Jether are the other two.
Moses said to Hobab son of Reuel the Midianite, Moses' father-in-law, "We are setting out for the place of which the LORD has said, 'I will give it to you.' Come with us and we will be generous with you; for the LORD has promised to be generous to Israel."
(Num. 10:29 TNK)
Now Heber the Kenite had separated from the other Kenites, descendants of Hobab, father-in-law of Moses, and had pitched his tent at Elon-bezaanannim, which is near Kedesh. (Jdg. 4:11 TNK)
Moses went back to his father-in-law Jether and said to him, "Let me go back to my kinsmen in Egypt and see how they are faring." And Jethro said to Moses, "Go in peace." (Exod. 4:18 TNK)
Jonathan Sarna in The Cambridge Dictionary of Judaism and Jewish Culture notes:
There is no scholarly consensus on this variety of designations, apparently indicative of diverse Israelite traditions.
He also notes:
To the four biblical names associated with Moses’ father-in-law, the Rabbis added Keni, Heber, and Putiel ( Mekhilta Yitro 1; Sifre Numbers 78) and expounded each to his credit.
Rabbinic traditions linked Jethro to Job and Balaam as Pharaoh’s counselors before the Exodus (BT Sotah 11a; Exodus Rabbah 27:6); appalled by Pharaoh’s plan to murder Israelite infants, Jethro fled to Midian and converted to Judaism.
