Amenemhat III
Sekhemre Khutawy Sobekhotep is attested by contemporary sources. First, he is mentioned on the Kahun Papyrus IV, now in the Petrie Museum (UC32166). (Ryholt, p. 315) This Kahun Papyrus is "a census of the household of a lector-priest that is dated to the first regnal year" of the king and also records the birth of a son of the lector-priest during a 40th regnal year, "which can only refer to Amenemhat III." This establishes that Sekhemre Khutawy Sobekhotep reigned close in time to Amenemhat III.
