Ptolemy XII Auletes
Cleopatra belonged to the Macedonian Greek dynasty of the Ptolemies, their European origins tracing back to northern Greece. Through her father, Ptolemy XII Auletes, she was a descendant of two prominent companions of Alexander the Great of Macedon: the general Ptolemy I Soter, founder of the Ptolemaic Kingdom of Egypt, and Seleucus I Nicator, the Macedonian Greek founder of the Seleucid Empire of West Asia. While Cleopatra's paternal line can be traced, the identity of her mother is unknown. She was presumably the daughter of Cleopatra VI Tryphaena (also known as Cleopatra V Tryphaena), the sister-wife of Ptolemy XII who had previously given birth to their daughter Berenice IV.
