Yest this is intriguing to say the least. Perhaps on of East Iranic Sarmatians from Ukraine ended up in Kurdistan. I can picture this happening during great migration period. They could have been pushed into Balkans and farther from Balkans pushed to Anatolia by Bulgars and Slavs. Sarmatians might have been linguistically East Iranian but genetically mostly local from Ukraine.
Parthians asked among the Sarmatians for help against the Romans and settled Sarmatian tribal groups on their Western borders. Those Sarmatian tribes ended up becoming Parthians themselves.
Adiabene had a mixed population. According to
Pliny, four tribes inhabited the region of Adiabene:
Orontes,
Alani,
Azones and
Silices.
Based on names of the Adiabene rulers,
Ernst Herzfeld suggested a
Saka/
Scythian origin for the royal house of the kingdom;
[16][17] however, later progress in Iranian linguistic studies showed that these names were common west middle Iranian names.
[18] It has been suggested that the royal house of Adiabene after fleeing Trajan's invasion, established the later
Amatuni dynasty who ruled the area between lakes
Urmia and
Van.
[19][20]
The ruling tribe was Parthians.
Orontest were most likely a local Parthian tribe. Alani = Alans, Azones and Silices = also Sarmatian tribes. Unfortunately we can't rely more on Wikipedia because of allot of spammers who have turned the history of Adiabene into "little Assyria/Armenia" despite the locals beeing of Iranic origin and under Parthian rule.
It tells the tragic story of two young people in love. Mem, a young Kurdish boy of the "Alan"
clan & heir to the
City of the West,
There is a famous Kurdish poem of Mem, a Kurdish boy of the Alan tribe and Zin a girl from the local Butan/Botan tribe, which is most likely the Buddi tribe of the Medes, since the people traditionally call themselves also Boti/Buti.
This poem stems from my home region. And the people there say we are descend of Mem the Alan. This should explain why I chose this Username.

I have said it in the past and can only repeat myself. Kurds are descend of Parthians who themselves are the middle Iranic descend of the Medes. Medes=> Parthians=> Kurds.
BUT Iranic tribes were very mobile people. And during the Median, Parthian and even Sassanid periods many Iranic tribal groups moved and settled among their other Iranic cousins. For example some Medes/Parthians went so far and settled on the Balkans according to Heredotus and some other sources I have seen.
We have found many evidences for that for example Scythians and Cimmerians settled in Media and became Medes themselves. According to Carola Metzner-Nebelsick the Scythians and Cimmerians who became locals in Media started to call themselves Medes too.
We have to realize and see the relation between those tribes. They were close cousins and acted as such. Back than the linguistic difference between East and West Iranic must have been more like that what you find among dialects of some languages.
And about the Sarmatian, they came from East of the Caspian and settled above the Scythians. Genetically, just like Yamna they were most likely something in between North Caucasians, Udmurts,Mordovians, Ukrainians and ancient Central Asians, but in comparison to Yamna leaning stronger towards North Caucasus/Central Asia.
