I see, you are right, but I was answering to a more general point made by OP, that if those who speak your language arrived late, you could still have a connection with those who lived there before.
You are right, but just to nitpick, linguistic ancestors don't always overlap with genetic ancestors. It could well be that your linguistic ones stumbled there late, whereas your genetic ones lived there for thousands and thousands of years longer. A handful of people can convince many to change language, genetic change is much slower. This is one reason why people in the region are genetically relatively similar, whether they speak slavic, germanic, finno-ugric, or latin languages.
For all these reasons, if etruscans once lived where you live now, it would actually be rather surprising if you had no connection whatsoever to them.
