"Who" is my brother's wife's sister's daughter? My niece?

Question:

"Who" is my brother's wife's sister's daughter? My niece?

Hi, what family relative would be my brother's wife's sister's child?

Is she my niece, or my niece once removed? or second niece? She is the offspring of the sister of the woman my brother married, so she's not a blood relative of mine, but she must be referred some sort of "relative" to me since she is my brother's niece.

How does one determine? Is there a website? My son is always asking.

Who would she be to my son? A 2nd cousin or something like that?

Also, who is my husband's cousin to my son? His great cousin? 2nd cousin or cousin once removed?

Thanks

Best Answer - Chosen by Asker: shes not related to you. she is related to your brother by marriage, but not to you. they are just people.... like your son is going to understand that whole cousin once removed stuff anyhow. your husbands cousin is your husbands cousin. as far as anything else is concerned, why???? forget all of that 2nd cousin & removed stuff. what does it really matter???
