Is it taboo to marry your brother's sister-in-law? Your brother's wife's sister?

At one point in life I knew a set a twins that married another set of twins… Brothers married sisters. So I wouldn’t see what was wrong with that even though it sounds really bad.

Depends if the other in question is male and has any genetic relation to the sister .

{thearbitrator] 🤷‍♂️ cannot see any problem keep it in the family 😆

I know three families who did that, and everything worked out great.

They're not blood relatives so no, why should it matter?

No. My Mom's sister married my Dad's brother.

No, why?

Why would it be?

I don’t see why

Nah

No
