In a small town with one prosecutor (a position previously held by the current judge), would it be odd for the Judge to hear a case involving that Prosecutor's immediate family concerning a custody dispute? Note; a motion for Recusal/Disqualification was filed but quickly denied.

I guess, I am just wondering if my dad being the PA and the judge being a lifelong family friend could help my ex in appeals? (I did receive a very favorable ruling that I hope will stick beyond appeal).

Just curious as to any opinions, thank you!
