.... according to ancestry the person I am looking at is" the wife of the husband of the sister in law of the uncle of the wife of the uncle" ....
I think there's seven people there....
So I think the person you are looking at is a female (the wife of) and she is a married person (wife ) so there's TWO people there ...
THEN reading the sentence from the end to the beginning.
.. so two more people ... wife of the uncle
... two more people .... sister in law of the uncle of the wife of the uncle
... one more person ... husband of the sister in law of the uncle of the wife of the uncle
Seven people

I cannot see that the person you are looking at is related to you.
