One of the wildest "seven degrees of separation" links but...

Tiffany Trump, daughter of Donald, has fiancee Michael Boulos.  He has a brother Fares Boulos who is an actor.  Fares played Ken Russell in a very very brief scene in the British series The Crown about the monarchy.

Actually it  takes place at a party and someone says something like "Ken Russell is over there" pointing at a mass of people.  It lasts for under 10 seconds and I didn't see who in the crowd they were referring to.

The article which came up with this link is by (and I quote) "NICK CRAVEN and DAVID ENDERS IN BEIRUT and SAMUEL OKOCHA IN LAGOS, NIGERIA and GARY O'SHEA FOR MAILONLINE" in the mailonline 23 Jan 2021.
