What is the relation to you of your sister's sister-in-law's daughter?

Answer 1

There are three possibilities:

1. If you are male, your sister's sister-in-law could be your wife. Then the sister-in-laws's daughter is yourdaughter.
2. Your sister's sister-in-law could be the wife of your brother. Then the sister-in-law is your sister-in-law, too, and her daughter is also your brother's daughter and thus your niece.
3. Your sister's sister-in-law could be the sister of your sister's husband. Then the sister-in-law is not related to you, and neither is her daughter.

Answer 2

Your father's sister is your aunt.

Your father's sister's mother is your grandmother.

Your father's sister's mother's ( your grandma's) only sister-in-law would usually be your father's wife, and therefore your mother.?

But if your father was never married then term daughter-in-law would not apply to your mother, despite the fact of your existence. If your father had a brother who married then your grandma's only daughter-inilaw would be your aunt on your father's side.

Answer 3

If your brother-in-law is the brother of your wife, then one of his sisters is your wife and any others are your sisters-in-law.

If your brother-in-law is the husband of your sister, then his sisters are not related to you, but they are your sister's sisters-in-law.
