Question:

Is my mom's uncle's son's wife's sister related to me?

Best Answer - Chosen by Asker: If you and the wife's sister share any ancestor, you are related. If you don't , you are not.
Nothing you say here proves anything, either way.
My daughter and her husband share a DISTANT ancestor. They are related. 9th cousins 4 generations removed are "related" but it ain't incest.
