1 Chronicles 8:33-34 -

The number of Saul's children was certainly nine. In addition to the four ( 1 Samuel 31:2 ) mentioned here, there was Ishui, probably standing second ( 1 Samuel 14:49 ), and there were two daughters, Merab and Michal ( 1 Samuel 14:49 ), and there were two sons by Rizpah ( 2 Samuel 21:8 ), named Armoui and Mephi-bosheth. Esh-baal ; the same with Ishbo-sheth ( 2 Samuel 2:8 ; 2 Samuel 3:7-14 ; 2 Samuel 4:4-12 ). Merib-baal ; the same with Mephibosheth ( 2 Samuel 9:12 ). Micah is, therefore, the great-grandson of Saul.
