Amenemhat III
The relationship of Amenemhat IV to Amenemhat III is debated; Amenemhat IV was the son of Amenemhat III according to Manetho, but given the age gap of 84 years, some historians believe he was a grandson. However, Neferuptah, the only sister who was older than Sobekneferu, died before Amenemhat IV's birth, as Sobekneferu is mentioned as heir presumptive at some point in her father's reign and thus cannot be Amenemhat's mother and there is no record of another son of Amenemhat III, and had he existed, he would be the heir, not Sobekneferu. Manetho states that Amenemhat IV married his sister Sobekneferu, who is identified as a royal daughter of Amenemhat III and eventually became king upon the death of Amenemhat IV. Manetho's claim about the marriage was proved wrong. Particularly inconsistent with Manetho's records, Sobekneferu is not known to have borne the title of "King's Wife" among her other titles. Egyptologist Kim Ryholt proposes alternatively that Amenemhat IV was a son of an earlier husband and was adopted by Amenemhat III and thus became Sobekneferu's stepbrother, thereby explaining the Manethonian tradition.
