I believe the information in the edit I added was already sourced. In the description for Amenemhat, he is described as "a prince of the
Eighteenth Dynasty of Egypt; the son of Pharaoh
Thutmose IV. " and the source given is [10], "Dodson, Aidan; Hilton, Dyan (2004). The Complete Royal Families of Ancient Egypt. London: Thames & Hudson." Checking the source already listed shows that the son of Thutmose IV is indeed Amenemhat, but specifically Amenemhat IV. I believe whoever added him to the table likely just forgot to complete his title.
