My family come from an small village near Paphos,if you remember,and it is true that in our region old people spoke Greek only.I remember helping my grandmother learn Turkish,but you are right,her first language remained Greek upto her death in 1972. I have not heard the GC claims you are talking about,but it makes sense that if this scientific study is true most of us have come from the same racial stock.In former Yugoslavia many slavs under the Ottomans converted to Islam for one reason or other,and hence the Bosnian nation came about.There is no reason to doubt that the same thing has not happened in Cyprus.
I also suspect that during the Ottoman rule there were a lot of intermariages between TCs and GCs,which were supressed under the British rule. As you know the British policy in Cyprus was "devide and conquer" so it didn't suit them to have one strong Cypriot nation under them.
As to why Denktash would want to suppress such a report,I think the reason is obvious. The same reason why TMT operatives would go around at dead of night painting anti-Turkish slogans in Greek and with blue paint on mosques in Cyprus.
Oh,brother Kifeas,please think of me when you next walk under a fig tree or a carob tree in the hills around Paphos.And if you go olive-picking remember to pick some for me
