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,
If your niece's is by your sister but the brother is by your sisters new husband & another woman there would be no blood relation. If not then he's the nephew
Carrie was the adoptive mother of her widower husbands son and daughter, but she had no children of her own.
The answer is: herself or one of her sisters. Her mother's son is her brother, and she and any female siblings would be her brother's son's aunt.
If two people are brother and sister and the sister has a son, then: her brother is her son's uncle, and her son is her brother's nephew.
He is your step son.
