no mention here: https://en.wikipedia.org/wiki/Khalyzians
there is evidence of a Celtic tribe in Anatolia https://en.wikipedia.org/wiki/Galatia

maybe the name drifted from there

By the 4th century BC the Celts had penetrated into the Balkans, coming into contact with the Thracians and Greeks.[5] In 380 BC they fought in the southern regions of Dalmatia (present day Croatia), and rumors circulated around the ancient world that Alexander the Great's father, Philip II of Macedonia had been assassinated by a dagger of Celtic origins.[6][7] Arrian writes that "Celts established on the Ionic coast" were among those who came to meet Alexander the Great during a campaign against the Getae in 335 BC.[8] Several ancient accounts mention that the Celts formed an alliance with Dionysius I of Syracuse who sent them to fight alongside the Macedonians against the Thebans.[9] In 279 BC two Celtic factions united under the leadership of Brennus and began to push southwards from southern Bulgaria towards the Greek states. According to Livy, a sizable force split off from this main group and head toward Asia Minor.[10]
