The matches are as follows:
- Son and successor of Josiah = JEHOAHAZ
- Brother and successor of Jehoahaz = JEHOIAKIM
- Father of Zedekiah (Mattaniah) = JOSIAH
- Son and successor of Jehoiakim (Eliakim) = JEHOAICHIN
- Last king of Judah = ZEDEKIAH
There's a bunch of the family tree of Josiah in that mix. Hopefully you can keep it all straight!
