Gavin Newsom. There is talk of him being related to Nancy Pelosi. Nancy is not his aunt but…
Wikipedia shows that Gavin's father William had a sister "Barbara" that was one time the wife of Ron Pelosi, Paul's brother.

Barbara and Ron, in 1970, lost two of their children (daughters) and the babysitter in a housefire.
