It generated me an Anatolian farmer from the 19th century who spoke... Ottoman Turkish. It's like taking a peasant Briton from the 1200s and claiming that they spoke French, because it was an official language of the country back then. (Ottoman Turkish was an artificial literary register which was incomprehensible to most of the population.)

I hope that the author learns from the comments in this thread that dry encyclopedic data does not define reality.
