According to 1 Kings, King Abijah’s mother Maakah was the daughter of Abishalom. Then in 2 Chronicles, it says she was the daughter of Absalom. That’s probably supposed to be the same name, just written a little differently.

(From the context, it sounds like that likely means David’s son Absalom. That would mean Abijah’s father Rehoboam married his cousin, which might seem weird and unlikely to some people, but note that there are two more first cousin marriages mentioned right there in that same passage. Absalom’s mother was also named Maakah, so maybe he named his daughter after her.)

Two chapters later, though, it says Maakah was the daughter of Uriel of Gibeah. That doesn’t sound like the same person at all. Absalom was born in Hebron, not Gibeah.

Possible explanation

Maybe Uriel was Maakah’s mother?
