Note:

The rules that dictate who can and can’t be a Prince or Princess are complicated, though the sovereign can alter them as they see fit.
Usually, all legitimate children of the sovereign are titled Prince/Princess.
This is at the sovereign's discretion.
All children of the Prince/Princess of Baile Uí Bhrolcháin are titled Prince/Princess.
All other grandchildren are titled as the sovereign deems appropriate.

Siblings of the sovereign are usually titled Duke or Duchess, except the eldest sister or daughter will be Princess Royal.
All of the sovereign's siblings' children shall be titled as Sir/Lady unless otherwise titled.
For all of the sovereign's siblings, only the eldest recognized child surviving will inherit the ducal title.
