She's pregnant
Its would be your neice
The brothers of your spouse are your brothers-in-law. Also, the husbands of your sisters are your brothers-in-law.
Your brother's daughter is your niece..and you are her AUNT.
Great Niece.
YES
Let's see if we can unravel this. Your sister's husband's father's brother is your sister's husband's uncle. The uncle's daughter is your sister's husband's cousin. There is no relationship to your sister, unless your sister wants to call her a cousin-in-law. To break it down to its simplest terms: She is your brother-in-law's cousin and no relationship to you.
You are their aunt or aunt by marriage.
First cousins twice removed.
That would be her great uncle I suppose. Common sense.

Your younger brother's wife's sister's daughter would be your son's cousin.
Your brother would be your son's daughter's great uncle and your son's daughter would be your brothers great niece! Hopefully that makes sense :)
