托勒密十二世
Other historians suggest Cleopatra VI Tryphaena may be identical with Cleopatra V Tryphaena, the only recorded wife of Ptolemy XII Auletes. Cleopatra V Tryphaena was Queen consort of Egypt from her marriage to Ptolemy in 79 BC until her mysterious disappearance from the records in 69 BC. Some historians believe her disappearance in 69 BC was due to her death. However, a dedication on the Temple of Edfu from December 5, 57 BC reads, "Ptolemy, Young Osiris, with his Sister, queen Cleopatra, surnamed Tryphaena." The king is Ptolemy XII (who however was not present in Egypt at that time). The "Cleopatra Tryphaena" named by the inscription would be the king's wife rather than daughter, and it is unlikely the name would appear had Ptolemy XII's wife already died twelve years earlier. If Cleopatra V was indeed still alive in  57 BC, and in view of the account by Strabo that Ptolemy XII Auletes had only three daughters, some historians think it most likely that Berenice IV's co-queen was her "mother", Cleopatra V Tryphaena, rather than (as Porphyry has it) an otherwise unattested "sister".
