A Right Royal Heeps

[Butty Brennan]

Let's have a quick game of Heeps so I can try out the new sheepulator.
This game will have a distinctly royal slant, remember in Heeps you want to choose the second most popular answer as the sheep scores a zero.
Here are One's questions:

Please name a:
Fictional princess
High King of Ireland
Monarch who was executed
Actress who played Queen Elizabeth II
Member of the British Royal Family
Monarch who died in battle
Actor who played King Henry VIII
One of King Charles III's sons
Song by Prince
Item associated with royalty, apart from a crown.

PM me your answers and don't hang around as I aim to reveal sooner rather than later.
