My point, exactly. He is not her nephew. Read what you wrote. Gavin's dad's sister was married to Nancy's brother in law. How does one have a brother in law? Well, it could be your sister's husband or it could be your spouse's brother. In this case it appears that Nancy's husband's brother was married to Gavin's dad's sister.
So in no way was he ever Nancy's nephew in law. And a 'nephew in law' is far from a nephew. No biological relation.
