Should a judge recuse himself if the defendant has filed an ethics complaint against a member of that judge's family?

Some years ago, I filed a complaint against a judge for somewhat dubious conduct. Recently, a close relative of that judge heard my case and made a rather hostile ruling on what seemed like a reasonable motion.

Of course, I cannot "prove" that this second judge was aware of the earlier complaint, so I doubt that anything can be done. Nevertheless, I am curious. I have seen judges recuse themselves for far more benign reasons that this one.

If the judge ought indeed have recused himself, I shall be looking for an attorney to file the necessary motions to overturn the verdict.
