Ah, blame me being an American who has never given a crap about royalty or nobility, living or dead ... and there’s no magic in old Hollywood or old DC either (in fact we didn’t need so many federal monuments to national glory until the process of kicking the Constitution to the curb in favor of Arbitrary government was well underway, especially after FDR oozed his way across history).
Yeah, I get that. Knowing the taxonomy of the nobility is helpful when reading Shakespeare, though.
