Lumsdale - to cut a long explanantion short, the people living in the part of Turkey known as Troy did not speak Latin in 1100 BCE. Had they settled and named London they would have done so in their own language which would have been at that time Hittite, which was written in cuneiform script. They did not call their own area 'Troy' so why they would call another settlement New Try doesn't add up.
The people of this part of Turkey later came into the Greek-speaking world, and even in Roman times Greek was the lingua franca.
