Does the duchess of Cornwall cursty to prince willian and harry?

Answer 1

The Queen has recently issued new guidelines on this very topic. Broadly speaking, members of the Royal family who were not born royal must curtsey to those that were. However, as with most Royal protocol this is nuanced.

The Queen's grandchildren are clearly of direct Royal lineage (even if Princess Anne's children bear no titles). Thus, non-royals who married into the family (notably the Duchess of Cornwall, the Duchess of Cambridge, and the Countess of Wessex) must curtsey to them, and indeed to all 'blood royals' including, on principle, William and Harry. (Though it is hard to imagine Catherine curtseying to her husband.) BUT, and it's a big but, when the three ladies mentioned above are accompanied by their 'true royal' spouses, they are not required to curtsey, except to the Queen (to whom even their husbands bow).
