You are not related to your sister's husband's brother. However, her husband is your brother-in-law and his brother is your sister's brother-in-law.
They are sisters in law.
Of course you could. But you're implying to incest and this is definitely not incest.
Yes, because your daughters are sisters and since their husbands are your son in law's that would make them brother in laws.PS. I hope your daughters are veryhappy, congrats!! :) ,,Chameleon5,
that would be the persons brother-in laws-cousin which would be too frickin far to have any sort of real name!!!!!!
My brothers-in-law are my sisters' misters. I don't know which of the sisters' husbands he is.
No, I don't know thing so. Cause he isn't your blood or related to u in anyway expect by sister's marriage. Your brother in law if you are female is either you husbands brother or the husband of your sister, so i assume you must mean the brother of your sisters husband. This is two sisters marring two brothers and i think it is very common. But You should as your brother in law .
Well, it depends how close you are to your husbands family. If you really want to know they are cousins-in-law.
He is brother your brother in law.
Your brother would call your husbands sister by her first name. Or, "my (sibling's) sister in law.

You would call your husband's younger brother a brother-in-law.
