N in Balts

[Parastais]

Since Anthrogenica got closed, also this thread dissappeared. 
So far, not much new info was available, but now we have another 4 samples from Lithuania, 3 of them under N-L550:

CGG_0_17685 G-Z31461 Roman Iron Age Marvele (Flat burials of central Lithuania).
CGG_0_17690 N-L550 400-700 AD Berciunai (North Lithuanian Barrows Culture).
CGG_0_17691 N-L550 400-700 AD Kaireneliai (Central or North Lithuanian Barrows Culture?).
CGG_0_17685 N-L550 8th-9th century Maudžiorai (Samogatian with some Curonian influence).

So far from early centuries AD we got another 1 sample from NLBC (Lithuania_IA poor quality) which was under L550, and 2 other samples from Marvele (also under L550). and 1 R1a sample from Bailuliai (same subclade under CTS1211 as Latvian Kivutkalns samples and ca 10% of modern Balts Y). 

Marvele G guy is an outlier and has genetics mostly resembling those of Caucasus + some steppe vibe. So, he is a visitor. 
Locals so far from first millenia AD are 6 N-L550 (2 Marvele, 3 NLBC, 1 later Samogitian) and 1 R-CTS1211 (East Lithuanian Barrows). 

What can be clearly stated:
1) NLBC and Central Lithuanian cultures were already N-L550 rich;
2) East Lithuania needs more samples

So, it is clear that N-L550 Baltic lineages did not arrive into Baltics together with East Balts/ Dnieper Balts or something after 500 AD. They were there already since at least beginning of CE and 'Barrows with Stone Rings' derived cultures.

Still no samples from Lithuania 1M BCE. 

G25 of new samples still not available. So, that is it for now.

Another interesting case is that again Oland sample turns out N-L550. So, iron age Baltic islanders were quite L-550 rich as well.
