Was Abiathar the father or the son of Ahimelech?
Abiathar was the son of Ahimelech. Abiathar was the father of Ahimelech.
1 Samuel 22:20
And one of the sons of Ahimelech the son of Ahitub, named Abiathar.

1 Samuel 23:6
Abiathar the son of Ahimelech.
2 Samuel 8:17, 1 Chronicles 18:16, 24:6
Ahimelech the son of Abiathar.
Oxford Annotated Bible note for 2 Samuel 8:17: Ahimelech the son of Abiathar should perhaps be reversed (1 Sam.22.20), though is is also possible that Abiathar had a son Ahimelech who acted in place of his aged father (1 Chr.18.16; 24.3,6,31).
Biblically Correct answer: Abiathar was the son of Ahimelech

I'll go with what the Oxford Annotated Bible said was most likely.
