Meritites IV

Meritites IV (also known as Meritites II as she was the second "queen" by that name) was a queen from the Sixth Dynasty. She was believed to be a wife of Pepi I Meryre, but her title of "King’s Daughter of his body of Pepy-Mennefer" ("s3t-niswt-nt-kht.f-ppy-mn-nfr") is now understood to indicate that she was a daughter of Pepi I Meryre and wife of a king Neferkare, presumably Pepi II. One more evidence for that theory is that her name means "Beloved of her father".
Titles.
Her titles include: "Great one of the hetes-sceptre", "She who sees Horus and Seth" ("m33t-hrw-stsh"), "Great of Praises" (wrt-hzwt), "King’s Wife" (hmt-nisw), "King’s Wife, his beloved" ("hmt-nisw meryt."f), and "Companion of Horus" ("smrt-hrw").
Burial.
Meritites IV was buried in Saqqara. Her pyramid lies to the south of the pyramid of Pepi I. Meritites' pyramid lies to the southwest of the complex of Queen Inenek-Inti and to the south of the queen's pyramid referred to as the "Southwestern pyramid".
