'Genealogies' in the Bible

All these were reckoned by genealogies in the days of Jotham king of Judah, and in the days of Jeroboam king of Israel.

So all Israel were reckoned by genealogies; and behold, they are written in the book of the kings of Israel: and Judah was carried away captive to Babylon for their disobedience.

Now the acts of Rehoboam, first and last, aren't they written in the histories of Shemaiah the prophet and of Iddo the seer, after the way of genealogies? There were wars between Rehoboam and Jeroboam continually.
