 One report of the period backs this account, describing Marcu as a "son" of the Köprülü family, therefore also Turko-Albanian.Petru Cercel may have also had an official wife, whose name is recorded as "Stanca", and who is sometimes identified as Marcu's mother.Whether or not she was another name for Sultana, or another Turkish wife, or simply Marcu's stepmother is uncertain, but all are viewed by historians as likely hypotheses.
