Andrew MangoAtatürk: The Biography of the Founder of Modern Turkey, Overlook Press, 2002, ISBN978-1-58567-334-6, p. 25; p.27. "Feyzullah's family is said to have come from the country near Vodina (now Edessa in western Greek Macedonia). The surname Sofuzade, meaning 'son of a pious man', suggests that the ancestors of Zübeyde and Ali Rıza had a similar background. Cemil Bozok, son of Salih Bozok, who was a distant cousin of Atatürk and, later, his ADC, claims to have been related to both Ali Rıza's and Zübeyde's families. This would mean that the families of Atatürk's parents were interrelated. Cemil Bozok also notes that his paternal grandfather, Safer Efendi, was of Albanian origin. This may have a bearing on the vexed question of Atatürk's ethnic origin. Atatürk's parents and relatives all used Turkish as their mother tongue. This suggests that some at least of their ancestors had originally come from Turkey, since local Muslims of Albanian and Slav origin who had no ethnic connection with Turkey spoke Albanian, Serbo-Croat or Bulgarian, at least so long as they remained in their native land., But in looks Ataturk resembled local Albanians and Slavs.[...] But there is no evidence that either Ali Riza or Zübeyde was descended from such Turkish nomads." page 28; "It is much more likely that Atatürk inherited his looks from his Balkan ancestors.[...] But Albanians and Slavs are likely to have figured among his ancestors."
