Was my ancestor a Roman soldier?

[Peterski]

Even if not Celts per se, then between the year 1 and 1800 is a lot of possibilities, how gaulish guy came to Polania.
Take for example Samo. 600 CE. Gall Anonim 1100. Stoiński aka Statorius 1550. Chopin 1800. No Roman legions at all.
In XVII century in 13,000 Warsaw lived 1000 Frech people. Look here: https://pl.wikipedia.org/wiki/Francuzi_w_Polsce

Should their descendants think, they came here with roman soldiers, only because they are ignorant about how they came here?

But it seems that my closest Y relatives are Spanish and Mexican, not French.

Sounds like Roberto went on a sex trip for the week end up north.

Then there should be something in autosomes, and there is not even 0.1%. Must be ancient admixture.

Maybe Robertus Maximus during the Marcomannic Wars. BTW, could be some "Amber Road" trader too:

I swear over the years the weirdest members of the forum have always been Poles.

Under this subclade there seems to be only my father (the one with BigY is my father actually, not me) and one Mexican guy:

Yes, from Hispania Romana.

What's the YBP of your last positive allele?

[Vrazijadivizija]

Well we all have a bunch of ancestors which probably back then were under Roman rule and most likely were serving their army no matter their origin.

Ok, the same. In 1800 years which are between supposed Romans in Lechia and you, anthing could happen.
Spanish soldiers did fight even in Moscow, so... Take unto account merchants, missionaries, or just regular
people moving here and there... There is so many surrprized movements of people, that without knowing the
real recorded history any guessing is futile. And btw, you still do not have confirmed haplogroup.

For example take unto account such scenario: some Vikings could raid Spain in 800s, take slaves, and move them to Sweden.
At 1300 swedish guy settled in Danzig. At 1600 some moved to Posen, and here you are... thinking about Roman Legions in Wartheland.

You mean the TMRCA? I'm not sure, they haven't updated it yet here: https://www.ytree.net/

For FGC31068 it is 2900 YBP (according to YFull), but that's not the last positive - there is one more after this.

Probably YBP is in Roman times (I guess ca. 2000 YBP, around the beginning of Common Era).

That's why snpTracker shows "Roman".

Well we all have a bunch of ancestors which probably back then were under Roman rule and most likely were serving their army no matter their origin.

Actually they could also serve in barbarian armies opposing the Romans. Or have no contact with the Romans.

Well obviusly yeah..we have ton of ancestors from every possible side would be amazing to be able to actually see and know who and what they were doing back then.
