Köprülü family
Some uncertainty also covers Aaron's matrimonial alliances. One interpretation of period texts suggests that he was the son-in-law of the Ottoman Greek businessman and kingmaker, Andronikos Kantakouzenos; also according to this reading, Kantakouzenos' other daughter was married to Wallachia's Stephen the Deaf. This take was rejected by historian Matei Cazacu, who notes that it is based on a mistranslation by Iorga. Several contemporary accounts mention that Aaron was in fact married to a former wife or concubine of Wallachia's Prince Petru Cercel, whose name was probably Stanca. She was most likely the mother of Marcu Cercel, and possibly also of his brothers Ionașcu and Radu Petru. Stanca may have been an ethnic Turk and a Muslim apostate whose original name was Sultana, and was perhaps also a renegade member of the Köprülü family.
