The title of King’s Brother is unknown until it was used in relation to Tjahapimu, the father of Nakhthorheb during the Late Period. However, Senet Nesu (King’s Sister) was used occasionally during the Middle Kingdom, and then a little more often during the New Kingdom. It seems to occur most often where either the woman in question was the sister-wife of the king, or where the woman was married to a foreign dignitary as part of an alliance or treaty. It seems also to refer to the sister of the current kings, rather than to an earlier king.
