How is that even a question? First of all Ayn Al-Arab is the official name and it's part of the Syrian Arab Republic.
Secondly all of Northern Iraq and Syria are ancient Semitic lands. Inhabited by native Semitic peoples such as Assyrians, Chaldeans, Arameans and Arabs who all have a several millennium old presence in the Levant.
Kurds are by all means new arrivals from Northwestern Iran or wherever they came from which is subject for debate among scholars to this day. If they claim to be "Aryans" then they originate on the Pontic Steppe.
Ayn Al-Arab is moreover a mixed city.
If names of cities and history just became erased due to migration then I guess that some parts of London and its history belongs to Bangladeshi or Pakistani people and large parts of Paris to Arabs, Berbers and West Africans.

Anyway the Turkish-Kurdish conflict is not our business and let the ISIS retards and Kurdish militants kill each other off for all I care as long as the civilians are safe.
