1 Chronicles 2:42  (King James Version)
Now the sons of Caleb the brother of Jerahmeel were, Mesha his firstborn, which was the father of Ziph; and the sons of Mareshah the father of Hebron.
 


Caleb
This was not Caleb the son of Jephunneh, but Caleb the son of Hezron, and therefore called the brother of Jerahmeel: See the parallel texts:
2:9
