It doesn"t matter if the poll is made by GC or TC. Anyway I have a very practical answer. My mother and her family are from Baphos and my father and his family are from Nicosia. I think that easily gives me right to say my motherland is Cyprus. I don't think I have to add that I my father found our family records since Venicians and already my surname was Venician but it changed after 74 `politely` and become a Turkish surname (like most other `Turkish` Cypriot)
Halil, Yorgancioglu is neither a historian nor an academits. He is a well paid `nationalist` author and his historical references are mostly Turkish historians, which means what we wrote hasn't got a value as a historical information. (It is not polite to say all of them are lie or wrong but he is aware of that and if you have chance to talk with him, act like you know the real history and oppose his book, then you will see what happens)
Anyway if you are looking for good books, there is a book Kibris'ta Osmanlilar from a Cypriot History Proffosor, you can also check same information with Cyprus history book set of Hashmet Muzaffer Gurkan (the only problem is thi set is not chronologic)
Turkishness is another paradox, so dont mix it up with ottoman. Ottoman was not Turkish neither its authorities nor its people. Its native and official languages were Arabic and Persian. The `Turkish` language which they `used` in Ottoman time has no similarity with what they and us using now. The moden Turkish has came with Mustafa Kemal, it is a very young and raw language and a institude in Turkey (Turk Dil Kurumu) still responsible to create new words and we cannot say they were successfull so far (ex: oturgaçlı götürgeç = means bus)
The reason why we are using 'Turkish` and why they are using `Turkish` is completely different. I hope I will have time to explain it soon.
