Ptolemy XII Auletes
If Porphyry is correct, it is likely Cleopatra VI Tryphaena was the daughter of Ptolemy XII Auletes by his wife Cleopatra V Tryphaena. As such, Cleopatra VI Tryphaena would have been an older sister of the famous Cleopatra VII, and her birth year would be c. 75 BC. Porphyry's account is however flatly contradicted by Strabo, who reports Ptolemy XII Auletes only had three daughters: these can reliably be identified as Berenice IV, Cleopatra VII, and Arsinoe IV, leaving no room for Cleopatra VI.
