Absolutely true. However, by the time the Romans pulled out of Britain, a large fraction of soldiers were drawn from various Germanic tribes and some other former enemies. Northern Italy especially had a mixed population dominated by Alpine people going back at least 4000 years. In more recent times the Lombards, another Germanic tribe, conquered all of northern Italy in the 6th and 7th centuries...of course by? that time I think Rome had abandoned Britain. Nevertheless, the fact that your haplogroup specifies northern Italy is potentially critical as southern Italy would have been dominated by Mediterranean peoples. Rich history to dive into for you and possible connection to Roman Empire. DF20 I think is less interesting, but it does establish one's line in the British Isles at a very early period (pre Roman or Germanic or Viking invasion). Good luck!?
