Tabekenamun was a daughter of King Piye and may have been a queen consort to her brother Taharqa. She is known from Cairo Statue 49157 from Karnak.
Others have suggested Tabekenamun was the wife of Shabaka. She was a King's Daughter, King's Sister and King's Wife. In addition, she was a priestess of Hathor, Mistress of Tepihu (Aphroditopolis) and a priestess of Hathor of Iunyt (Dendera) as well as a priestess of Neith. The priestly offices could suggest she was a daughter of one of the Libyan Pharaohs.
