[Facts] Re: aylin is not a turkish name it is a greek name.
We assign the labels "Turkish" and "Greek" by actual usage, not by etymology. So, Eleni is the Modern Greek form of Helena, but Aylin is Turkish with debatable etymology. Aylin can also be of anglo-celtic origin, as a variant of Eileen used in Germany, finally also going back to Helena but the usage is German in this case.
