As for the third of Constantine's nephews, his subsequent career is harder to trace. There is, however, a possibility that when he emerged from the Palace he did so as Gedik Ahmed Paşa, who in 1473 was named Grand Vezir by Mehmed II. While little is known about the early years of Gedik Ahmed Paşa, the Turkish scholar Mükrimin Halil Yinanç has cited unnamed Western sources claiming that he was of Palaiologan origin. More recently, the 1985 study on the Serbian region of Vranje by Aleksandar Stojanovski, has established that Gedik Ahmed Paşa was a member of the minor Serbian aristocracy. In Stojanovski's study of a fifteenth-century cadastral survey (tahrir defter), a timar (fief) holder is listed as the newly converted "father of the illustrious Gedik Ahmed Paşa". This identification, while undermining Yinanç's suggestion of Palaiologan ancestry for Gedik Ahmed Paşa, would make him a member of the Serbian military aristocracy, since his father is shown to have previously held a pronoia (fief).
Angiolello’ya göre Sırbistan’da doğdu. İvranye’ye (Vranye) bağlı Punuševce (Polnosevce) köyünün diğer adının 1570 tarihli Tahrir Defteri’nde Gedik Ahmed Paşa olarak belirtilmesi doğum yerinin bu köy olduğunu düşündürmektedir. Ayrıca İvranye’de bir cami yaptırması ve vakıf tahsis etmesi de bu tahmini pekiştirmektedir.
