Mentioned in the Bible by name

Nimshi

Jehu, the descendant (son, grandson) of Nimshi [2 Kings 9:2], you shall anoint as king over Israel. Also anoint Elisha [which means "my God is salvation"], the son of Shaphath, from Abel Meholah [a city in the Jordan Valley], to be prophet and your successor.

And when you arrive there, look for Jehu, son of Jehoshaphat, son of Nimshi, and go in and make him rise from among his brothers and bring him into an inner chamber.

And Jehu, the son of Jehoshaphat, the son of Nimshi, conspired against Joram. And Joram guarded (protected, preserved) Ramoth-Gilead from Hazael, king of Aram.

And the watchman told him, saying, "The messenger came to them, but he is not coming back. His driving is like the driving of Jehu, the son of Nimshi, for he drives violently ("like a madman" – Hebr. shigaon)." [The word "violently" comes from the same root as that translated "mad" in verse 11. This is the meaning given by the Greek and Latin versions, but the Jewish historian Josephus explained the word as meaning: "Jehu traveled calmly and in good order." Jehu drove in a manner that was easily recognizable. The similar word shiggaion is used for psalms that have "sudden changes," see Ps. 7:0; Hab. 3:1.]

But it was to Ahaziah's destruction that God had determined he should come to Joram. When he arrived there, he went with Joram to meet Jehu, the son of Nimshi, whom the Lord had anointed to destroy the house of Ahab.
