I have a problem with my Haplogroup

[andre]

I would like to know more about my Haplogroup, because it is really strange for a Romanian (on the paternal side we are Romanian) to have I-cts10057 .. do you know how to advise me on some calculators? do you think he really came to Romania with the Goths, Gepids or in the Middle Ages with the Saxons?

Have you read this from Eupedia?
I2a2 is found in most of Europe and seems to have had a continent-wide distribution before the arrival of Neolithic farmers. Several Mesolithic I2a2 samples have been identified to date, mostly by Mathieson et al. (2017). This includes individuals from southern Germany (M223 from c. 7200 BCE), the Iron Gates between Serbia and Romania (Z161 from c. 6200 BCE), Latvia (CTS10057 from c. 5500 BCE) and southeast Ukraine (L699 from c. 5400 BCE and L701 from c. 5200 BCE).

Remains from the Late Neolithic Sredny Stog culture (4500-3500 BCE) in Ukraine and of the Chalcolithic Globular Amphora culture (3400-2800 BCE) from Ukraine and Poland, were also tested by Mathieson et al. (2017). All six individuals from the Globular Amphora belonged to haplogroup I2a2. The deeper clade was identified for only two of them, and both belonged to the CTS10057 branch, including one positive for the Z161 mutation. The Sredny Stog people carried a mix of I2a2, R1, R1a and R1b lineages. The two I2a2a individuals belonged to the CTS10057 and L701 subclades. L701 was also found in Copper Age Bulgaria. Other I2a2a individuals was also found in Neolithic Scotland (L1195 and CTS10057), Neolithic Spain (CTS616 and Z161) and Neolithic Hungary (CTS10057).

Your haplogroup seems to exist in Neolithic Eastern Europe. It came somehow to Romania. It could be either with some eastern Germanic tribes you mentioned or one of your ancestors could have just moved once to Romania autonomously. I understand you because I have also a very strange haplogrpoup. The best way to get more information is the Big-Y 700 or a similar y-dna test. You will get your specific subclade and your matches that will help you to make conclusions.

You can't change your y-dna..
