The recent paper on Georgian populations ( Gavashelishvili 2021 ) gathered new DNA from unsampled groups. One of this groups were the Armenians of Javakhk (Samskhe-Javakheti, Georgia). Those Armenians are labeled Erzrum because their origins are in that region of Turkey. They migrated to Javakhk in 1830. My patrilineal ancestor was amongst them. Given that they lived relatively isolated and didn't mix with Georgians and other Armenians we can have an idea how pure blooded (North) Western Armenian were looking in the first half of 19th century. Erzrum region represents an extra interest because it is close to historic Diau (Taochoi). Offcourse we keep in mind that no modern pop can replace aDNA, but at last we can have some data to conjecture.
To my surprise they are exactly the same as the academic average of Armenians. Strangely they have less affinity to Black sea Pontic region ( score less Ikiztepe near Samsun region ) and subsequently more Arslantepe. The addition of Kur-Arax ( the second table) do not change the overall balance of the shift toward Caucasus. They also score trace level of European ancestry which can be expected given the history of that region. But no extra affinity to Anatolia MLBA. Hamshen Armenians as expected are Pontic region shifted. The extra European affinity in Pontic region is present in all groups living there.
Honestly I don't know what to conclude. The reason why I can't conclude anything is because I don't know what do represent the Academic Armenian average. In reality what we need is not an average of all Armenians but rather at last two or three subgroups. Hopefully there is some advance in this direction. Let's hope that we will see soon new data.
One thing that is certain is that Erzrum region Armenians do not have extra Caucasian affinity. So all those talks about Kartvelian tribes living there looks like unrealistic claims.
Another thing is that the hopes of Carlos and co that Western Armenians will have extra affinity to Europe will not be realised.
PS Maykop_Novosvobodnaya is similar to Kur-Arax. So I first tested without KA then with it.
