Ottoman Turkish diplomat Mr Kemal Pamuk was introduced. The series was actually set around 1912. The Surname Law of the Republic of Turkey was adopted on June 21, 1934. Before then, Turks carried titles such as "Pasha", "Hoca", "Bey", "Hanim", "Efendi", etc.

"Pamuk" is a Turkish family name and it is impossible for the Turkish diplomat Mr. Kemal Pamuk to have this or any other family name since Turks did not have family names before 1934. On 21st of June 1934, a law was issued by the state that required every citizen to adopt a family name.
