Teddysbears - I think the answer to 25 is probably Queen Cleopatra. Although she was undoubtedly a queen - or whatever a female ruling Pharaoh is called - I don't think she is generally referred to as Queen C, whereas Queen Nefertiti usually is.
But I think there are just too many references to 'carrying on' that apply to Cleopatra but don't apply to Nefertiti.
