mother of Cleopatra I Syra, was born to king Mithridates II of Pontus and his wife Laodice, who had a mixed Greek and Persian ancestral heritage. While the identity of Cleopatra VII Philopator's mother is uncertain, she is generally believed to be Cleopatra V of Egypt, the sister or cousin wife of Ptolemy XII Auletes, who was the daughter of Ptolemy IX Soter or Ptolemy X Alexander I. Additionally, while the identity of her paternal grandmother is not certain, she is generally believed to be Cleopatra IV, via Ptolemy XII's father, Ptolemy IX Soter, or a Greek Alexandrian woman. Claims of illegitimacy were never used against Cleopatra in the extremely hostile propaganda campaign by Augustus, Michael Grant noting that if Cleopatra had been illegitimate, her "numerous Roman enemies would have revealed this to the world." Grant states that Cleopatra probably had not a drop of Egyptian blood and that she "would have described herself as Greek." Grant also proposes that Cleopatra's paternal grandmother may have been mixed Syrian and Greek, in line with the precedent of Persian and Syrian blood in the Ptolemaic line, and continues that "certainly she was not an Egyptian," noting there is no known Egyptian wife of a Ptolemaic king and there is only one known Egyptian mistress of a Ptolemy (from the 3rd century BCE). Lefkowitz writes that this Egyptian woman, named Didyame, was the mistress of Ptolemy II Philadelphus. She notes that among Ptolemy II's many mistresses, Didyame was specifically singled out because she was Egyptian, and not of the usual Greek stock among Ptolemaic mistresses (who included among Ptolemy II's mistresses, the courtesans Bilistiche, Agathocleia, Stratonice of Libya, and Myrto—whose coloring and ethnicity were not specifically pointed out like Didyame, "presumably because they were Greek"). She further notes that if she had any children by Ptolemy, they never became king (all Ptolemaic kings were regarded as fully legitimate save for Ptolemy XII Auletes). She contends that it is "misleading to suggest that the unique non-Greek mistress Didyame provides evidence of a common practice." Duane W. Roller speculates that Cleopatra VII could have been the daughter of a hypothetical half-Macedonian-Greek, half-Egyptian woman belonging to the priestly family of Ptah (the other main candidate he notes would be Cleopatra V/VI) located in Memphis in northern Egypt, but contends that whatever Cleopatra's ancestry, she valued her Greek Ptolemaic heritage the most. He further notes that "there
