Bible Notes Online - 1-Chronicles 8 - ESV
Commentary

v1-40: The family of Benjamin, including the family of Saul, who became king (v33).

The list in v29-38 also appears in 9.35-44. Note that this list includes 10 generations after Jonathan, Saul's son; Jonathan - Mephibosheth (Merib-Baal) - Micah - Ahaz - Jehoaddah - Zimri - Moza - Binea - Raphah - Eleasah - Azel - his 6 sons. This would take the line to around the captivity in Babylon. We know that Benjamites survived for centuries, as Paul could trace his genealogy to Benjamin (Phil 3.5).
