Real tangle isn't it? BTW there's some doubt that Ahmose, wife of Thutmose I, was a King's daughteras her only title is 'sister of the King, and that apparently refers to Thutmose. But Mutnofret may have been a princess, there is an inscription refering to 'the King's Daughter Mutnofret' and in her mortuary temple she is shown wearing the royal cobra.
It also seems unlikely that Thutmose was a King's son as he never refers to himself as such, nor is his mother called 'King's wife'. He was probably related somehow to the royal family, but not so immediately as a half-brother or nephew.
Oh, and there's some doubt that Merytre Hatshepsut was the daughter of her namesake. Again she never calls herself 'King's Daughter' though she was Great Wife and God's Wife of Amon. Again she *must* have been related - but how?
Darn the Egyptians for not inscribing nice, neat family trees on their monuments!
