How to address Medieval Royalty and Nobility?
Like another answerer said, most of these titles were not around in the middle ages. I was just looking through the Gest of Robyn Hode from the 14th century, and the characters in that seem to refer to the king as my lord, or my lord the king, and knights and abbots as "sir" or "master". I'd assume that Earls and Barons would also use these forms of address. For example: "...My lorde the kynge of Englonde, Graunte me myn askynge. "I made a chapell in Bernysdale, That semely is to se, It is of Mary Magdaleyne, And thereto wolde I be..." If you're writing a book set in the middle ages, it might be helpful for you to look through some middle English texts to get an idea of how people spoke to one another (especially people of different ranks). i.e. Sir Gawain and the Green Knight, the Robin Hood stories, Piers Plowman, and the Canterbury Tales should be easy to find online. Here's the Gest of Robyn Hode. It's very Yeomanly. http://www.library.rochester.edu/camelot... Also, you've left out important medieval dignitaries from your lists. You also need to think about how they would have addressed bishops, monks, and abbots. In terms of status; Kings were the most powerful lords in England. During the Saxon period there were Earls who were just other powerful landowners. After the Normans conquered, Barons replaced Earls, and Earls were introduced again later.
What are characteristics of inbred royalty?
Shades of Harriet Beecher Stowe (who thoroughly disapproved of such practices in the 19th century): Inbreeding has manifested itself in the French, Spanish, and German royal families through ---reduced fertility ---high infant mortality ---increased genetic disorders ---fluctuating facial asymmetry, most noticeably in the Hapsburg lip, a feature that was so prominent in Carlos II of Spain that he couldn't chew his food. Queen Elizabeth II and Prince Philip are 2nd cousins, once removed, as well as 3rd cousins (as linear descendants of Queen Victoria and Prince Albert). Queen Victoria and Prince Albert, in turn, were first cousins. But then, during the 19th century, marrying cousins was not necessarily reserved for royalty: Albert Einstein, Charles Darwin, and Edgar Allan Poe, for example, all married first cousins. Perhaps I shouldn't even mention Lord Byron's romance with his half sister? As far as your question about anger management goes, controlling emotions probably has less to do with nature and more to do with nurture. More to the point, for many centuries, the British Royals have felt a sense of entitlement, which is sometimes not tempered by noblesse oblige.
