Jethro is a Hebrew name meaning "abundance" or "excellence", borne in the Bible by the Midianite priest who was the father-in-law of Moses. In America it long carried a country flavor thanks to Jethro Bodine of The Beverly Hillbillies, while the British rock band Jethro Tull took its name from an 18th-century agricultural pioneer. Jethro climbed from number 3699 in 2000 to number 953 among boys' names in 2025, its first year in the US top 1000 in this century.
