The Anglos, Saxons, and Jutes were all tribes from what we’d call Germany. The Romans paved the first roads of London, and taught the Pagans about Jesus. And Rome was cosmopolitan, so it was a lot more than Italians in that army. England has also suffered under Danish/Scandinavian conquests small and large. The King Cnut was not a misspelling. His nephew, William is a Scandinavian settled in France.

So… as far as “blood and soil” goes, Britain, and her people, were always more of a group project.
