The identity of this queen has not yet been established with any degree of certainty and Dakhamunzu has variously been identified as either Nefertiti, Meritaten or Ankhesenamen.
Lepsius rendering of the names is lower right, and were originally in the upper right where Meritaten's cartouche is quite clearly shown.
Other women who have been suggested as candidates for the identity of this female ruler are Queen Nefertiti (her mother) and her older sister Meritaten.
