John Gill Commentary 2 Chronicles 11:20

"And after her he took Maacah the daughter of Absalom; and she bare him Abijah, and Attai, and Ziza, and Shelomith." — 2 Chronicles 11:20 (ASV)

And after he took Maacah the daughter of Absalom
Thought by some to be Absalom the son of David, his father's brother, and his uncle, and so married his cousin; but Absalom seems to have had but one daughter, whose name was Tamar, (2 Samuel 14:27), and the name of this man is different from his; he is called Abishalom, (1 Kings 15:2)

and Uriel of Gibeah ;
(2 Chronicles 13:2), of the tribe of Benjamin, whereas Absalom was of the tribe of Judah:

which bare him Abijah, and Attai, and Ziza, and Shelomith :
Abijah the firstborn, and who was successor in the kingdom, is the same with Abijam, (1 Kings 14:31) of the rest we nowhere else read.
