There are three possibilities:
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.
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.
There is no relation. Your not blood at all so your just really good friends.
There is no real relationship. Most families would refer to them as sisters-in-law.

Yes she has a daughter named Grace Penner!
If she is your sisters daughter then she is your neice :)
