Maachah in Wikipedia

Maacah (Codex Alexandrinus: Maacha, KJV: Maachah) is a non- gender-specific personal name used in the Bible to refer to: A child of Abraham's brother Nachor, evidently a boy. (Gen. 22:23,24) The wife of Machir, Manasseh's son. (1. Chr. 7:15-16) One of the wives of Hezron's son Caleb. (1. Chr 2:48) A wife of David, and daughter of Talmai, King of Geshur (ib. iii. 3), a near neighbor of the Maachathites. David begat Absalom and Tamar with her. A King of Gath, to whose son, Achish, Shimei's servants fled early in Solomon's reign (1. Kings 2:39). About a half- century earlier than this event, David with 600 men had fled to Achish, son of Maoch, King of Gath (1. Samuel 27:2); but the identification of Maoch is doubtful, though kinship is exceedingly probable. The wife of Rehoboam, King of Judah, and mother of Abijam; in 1. Kings 15:2 she is called the daughter (or granddaughter) of Abishalom, but of "Absalom" in 2. Chronicles 11:20, 21. Hence, she was a granddaughter of King David's wife Maacah (above). She was removed from her position as queen mother by her grandson Asa (ib. xv. 16) because she had been involved in idolatry. The wife of Jeiel. (1.Chr. 8:29) The father of Hanan, who was a man in David's army. (1. Chr. 11:43) The father of Shephatiah, who was an office man in David's time. (1. Chr. 27:16) The name is also used to refer to: A small Aramean kingdom east of the Sea of Galilee (I Chronicles 19:6). Its territory was in the region assigned to the half-tribe of Manasseh east of the Jordan. Maacah, its king, became a mercenary of the Ammonites in their war against David (II Samuel 10:6). It is probable that the city Abel of Beth-maachah in Naphtali (ib. xx. 15) derived its name from its relation to this kingdom and people.
