we know the goths and east germans came from the same german roo as west germans they would have had Mainly R1b s21 also alot of I1a1, I1a3, and I1a4 but mainly R1b s21. I dont see R1b s21 with I1 in most of Europe so i dont think it is from Germans
You are wrong there are no any proves that East and West Germanic people came from the same root. Furthermore, there are many reasons to believe that R1b-U106 folks have not been authentic Germanic people but were Germanized by R1a and I1 and I2 folks.
Concerning the origion of East Germanic people here's a piece from HISTORY OF THE WARS, III. (PEOCOPIUS OF CAESAREA)
There were many Gothic nations in earlier times, just as also at the present, but the greatest and most important of all are the Goths,
Vandals, Visigoths, and Gepaedes. In ancient times,
however, they were named Sauromatae and Melan-
chlaeni ; and there were some too who called these
nations Getic. All these, while they are distinguished
from one another by their names, as has been said,
do not differ in anything else at all. For they all
have white bodies and fair hair, and are tall and
handsome to look upon, and they use the same laws
and practise a common religion. (For they are all
of the Arian faith, and have one language called
Gothic ; and, as it seems to me, they all came origin-
ally from one tribe, and were distinguished later by
the names of those who led each group. This
people used to dwell
above the Ister River from of
old. Later on the Gepaedes got possession of the
country about Singidunum 2 and Sirmium, 3 on both
sides of the Ister River, where they have remained,
settled even down to my time.
