Her Northwestern degree provides a hint here.
Your average bimbo does not have a degree with a double major in two unrelated fields from a highly selective university.
One of her majors was International Relations. I saw a funny comment that she should receive an honorary doctorate for basically “winning” at the international relations game by marrying a UK prince. 
Will Princess Charlotte get the title of ‘Princess Royal’ when Anne and Charles both die?
I believe I have read that the title Princess Royal is awarded at the monarch’s discretion. Anne only received it as an adult in recognition of her significant charity work is my understanding.
LOL - It has been reported that Jessica Mulroney practiced her hip sashay for a month, ahead of the wedding in order o 'give 'em some Pippa" :))
Well, you listed all the preconditions - William has to be King and Anne has to have died.
Correct. So what may happen decades in the future is pure idle speculation. So in that vein, alternatively, in the era of (at least increasing) gender equality within the Royal Family, William (or Charles if still alive and on the throne) may decide to break with tradition and make Charlotte a duchess in her own right on marriage.
One of the Chicago papers had the headline: Northwestern Grad Marries British Guy. :))
Does a Dukedom carry down to heirs same as an Earl for example? Will Harry’s children inherit the dukedom?
There seems to be a lot of dukedoms being handed out…plus I don’t even know if there is any significance to the Cambridge or Suffex. I know these are towns in England. Does that mean they reign over the town of Cambridge? Do they have an estate in Cambridge?
Yes.
No.
Most of the names (for dukedoms anyway) are old titles were “put on a shelf” after the became extinct. The first (and only) Duke of Sussex was one of George III’s sons. Since he had no legitimate children, the title became extinct on his death. In theory, the monarch can make up any name for a Dukedom s/he wants, as George VI did with the Dukedom of Windsor. But other than that, all the current ones, like Cambridge, Sussex, York, Kent, Edinburgh, Gloucester, were in use previously but became extinct.
Only if they go out and buy one.
I also wonder about some of these things. For example, I know that the Duchy of Cornwall is a major source of Prince Charles’ wealth and will be inherited by Prince William, but I wonder what would happen to the Cambridge when William becomes Prince of Wales and Duke of Cornwall. Would he remain Duke of Cambridge? Would George move up?
Skieurope, I’ve so enjoyed your posts here.
Assuming William one day becomes king, he will hold the title of Duke of Cambridge until then, at which point the title merges with the Crown. He can then choose to make a new creation of the Dukedom and assign it to whomever he pleases. George will not “move up;” the only way he would automatically become Duke of Cambridge is if William dies before becoming King. George would likely get his own Dukedom on marriage.
If/when Charles becomes King, William will become Duke of Cornwall automatically, but will not automatically become Prince of Wales. Charles would need to create William as Prince of Wales. However, if Charles predeceases the Queen, William will not be Duke of Cornwall, as the holder can only be the monarch’s eldest son, but could be Prince of Wales should the Queen so choose.
Thank you.
@skieurope if you are ever a Jeopardy contestant you will nail the “English titles” category. Perhaps it has been mentioned, but how do you know all of this ?
Agree with zoosermom very interesting and complex.
It has been asked. IDK, I just somehow remember mindless stuff. Don’t get me started on Red Sox stats; I’ve been in many a Boston-area bar without having to pay for a single drink. 
Too funny.
@skieurope Do you have a title? No need to tell us what it is.
LOL. No
As long as they were going back to an oldie but goody like Stand by Me at the wedding, you’d think they could have fit this one in somewhere:
@skieurope, I heard that one of the major reasons for giving princes dukedoms when they marry is to create a convenient title for their wives, who would otherwise be something ridiculous like Princess Hisname. Is that correct?
Of course, since the whole world refers to the current young duchesses by their maiden names anyhow, maybe this is no longer a motivation.

@Marian My guess is no. The tradition of royal dukedoms in the UK goes back until at least the reign of Edward III, while, with a few exceptions, royalty marrying commoners is relatively recent.
