What would have been the expected courtesy title and style for a hypothetical daughter of Elizabeth I of England, assuming she wasn't made Princess of Wales? Tudor England seems to have been the point where it transitions from 'Lady Name' and 'my Lady Princess' to 'Princess Name' and 'Your Highness' but I haven't been able to confirm this.
ETA: She's assumed legitimate. (In other words she's one of those 'secret babies' the Spanish Court were so fond of believing in.)
The second question - I'm looking for information about doctors in the French Army in the last days of the Old Regime, the French Revolution and the Napoleonic Era. I have a character I'd like to have been a surgeon's apprentice as a child in the French Army when they were helping out with the American Revolution and somehow go from there to formal medical training to being a full-fledged physician; most probably by saving the life of someone important who then became his patron. Would this be plausible and, given the breaking-down of class barriers over the next couple of decades, would it be possible for him to be held in high-respect by the beginning of the Napoleonic era?
General resources about what he would have been expected to know would also be awesome.
For the first I've already tried googling "Princess Courtesy Title History", "Princess Courtesy Title Elizabethan" and variations thereof and I've been reading contemporary writing about the various Tudor kings' daughters to see how people referred to them. For the second I've tried "French Medical History", "Napoleonic Medicine" and "Revolutionary France Army Medicine" and such-like. Got a lot about the history of the guillotine but not much else.
