Passage: The family of the king is known from several sources. A monument from Sehel Island shows Sobekhotep with his father Mentuhotep, his mother was Iuhetibu (Yauheyebu), his brothers Seneb and Khakau, and a half-sister called Reniseneb. Reniseneb was a daughter of Iuhetibu and her second husband Dedusobek.Sobekhotep III had two wives, Senebhenas and Neni. A stela from Koptos (Qift), now in the Louvre (C 8), mentions the daughters of Nenni: Iuhetibu (Fendy) and Dedetanqet. Iuhetibu Fendy wrote her name in a cartouche. This is the second time in Egyptian history that a king's daughter received this honor.
