The suffix “in-law” is also used for those who marry your relations – for example, your brother's wife is your sister-in- law. (One exception is that your aunt's husband gets to be called your uncle, even though he is “really” your uncle-in-law; and similarly your uncle's wife gets to be called your aunt.).
Similarly, you may ask, is your uncle's girlfriend your aunt?
The co-uncle is the brother of one's spouse of one's sibling (uncle of one's niece or nephew who is not one's brother). The female counterpart of an uncle is an aunt, and the reciprocal relationship is that of a nephew or niece.
Subsequently, question is, what would my aunt's niece be to me? If you are male you would be your aunt's nephew. If your aunt is the sister of one of your parents her other nephews would be your brothers or your male first cousins. If she is an aunt because she is married to your uncle (the brother of one of your parents) then she is an aunt by marriage.
In respect to this, what do you call your uncle's wife's parents?
Your spouses parents are father/mother-in-law and you're their son/daughter-in-law. In your situation, in order to use as few words as possible, if the Uncle is the blood relation (i.e. my parent's brother) I'd say "my Aunt's parents", or if the Aunt is the blood relation I'd say "my Uncle's parents".
What is my uncle's wife's sister called?
From a strictly technical perspective, she is: your uncle's wife's sister. She is the sister-in-law of your uncle, and might be called a sister-in-law, once removed, from the parent whose sibling your uncle is.
