Who would name their kid Mephibosheth?

Mephibosheth was the son of Jonathan (David’s deceased best friend) and the grandson of the deceased King Saul. He was crippled in both feet.

King David asked Ziba, a servant of King Saul if there was anyone who was still alive from King Saul’s family and Ziba told him of Mephibosheth. King David had him come to the palace. And when they met the king showed great kindness to him. He told Mephibosheth that he would receive all the land that had belonged to King Saul and that he would always eat at the Kings table. Ziba and all his household would become Mephibosheth’s servants and farm the land that he now owned.
