Charles Ellicott Commentary 1 Samuel 14:51

"And Kish was the father of Saul; and Ner the father of Abner was the son of Abiel." — 1 Samuel 14:51 (ASV)

The son of Abiel. —For “son” the commentators mostly agree we must read sons. Kish and Ner, we know, were both sons of Abiel. (See 1 Chronicles 9:35–36, where, however, the father’s name is given as Jehiel.)
