On it's face this sounds like BS, but I can do some genealogy digs.
I will start with a few who I think would be least likely to be monarch affiliated. Kek
Be back in a while.
Genealogy fag here.
While searching for a link to any monarch re: Richard Nixon, I found this interesting and sad article regarding Pat Nixon and her family tree.

Will be back with more RMN news later.
That would be big, anon.
