What would my sister's husband's brother be to me?

Your brother-in-law.

I disagree. He would be your sister's brother - in - law, but nothing to you.

Three places down and across at the family reunion? That's about where the brother in law should fit.

I call my sister husband brother-in-law so that is why I said that.

Absolutely nothing.

Technically nothing. But that's no reason you can't have a brotherly relationship. Close familys are awesome familys :)

I agree with that. But when you take it a step further - to your brother in law's brother - it is not a family relation.

Okay, fifth down and across.
