Son: Caleb
All we know about Jephunneh is that he was a Kenizzite, a tribe only mentioned in Genesis 15:19, Joshua 14:6,14 & Numbers 32:12 who was father of Caleb - one of only 2 spies who God allowed to enter the promised land of Canaan. Because the census in Numbers 1:26-27 lists 74,600 males of military age listed for the tribe of Judah, it's not feasible to determine his exact origin among the lineages, although he does appear in the lineage of Judah in 1 Chronicles 4.
