As explained by Whitehorne (1994, p. 182), Cleopatra VI may have actually been a daughter of Ptolemy XII who appeared in 58 BC to rule jointly with her alleged sister Berenice IV (while Ptolemy XII was exiled and living in Rome), whereas Ptolemy XIIs wife Cleopatra V perhaps died as early as the winter of 69–68 BC, when she disappears from historical records.
