Well we've got to define something
... I'd opt for something like Latium natives of 750-300 BCE, adding Etruscans. My point is to exclude Magna Graecia, because it would make it harder to make an ethnocultural statement or conclusion.
Consider this: We do not, in fact, have to define something. We don't have to define an artificial genetic category just so we can then categorize people into artificial genetic buckets.
