Charles Ellicott Commentary 1 Kings 15:2

"Three years reigned he in Jerusalem: and his mother`s name was Maacah the daughter of Abishalom." — 1 Kings 15:2 (ASV)

Maachah, the daughter of Abishalom. The Abishalom of this passage, called Absalom in 2 Chronicles 11:20, is in all probability the rebel son of David, whose mother (2 Samuel 3:3) was also named Maachah.

In 2 Chronicles 11:21–22, it seems that of all the wives (eighteen wives and threescore concubines) whom Rehoboam, following the evil traditions of his father, took, she was the favourite, and that even in his lifetime Rehoboam exalted Abijam to be ruler among his brethren.

In 2 Chronicles 13:2, she is called Michaiah and said to be the daughter of Uriel of Gibeah. This shows that, as chronological considerations would indeed suggest, she must have been the granddaughter of Absalom.

She is mentioned below (1 Kings 15:13) as prominent in the evil propensity to idolatry.
