The ancestors of ALL Brit's originate elsewhere, so, what does that say about us?

I think it started with the Celts. Then came the Angles, Saxons, Jutes, Franks, the Norse and finally, the Normans. Since then, we have received many more but in smaller numbers, such as Huguenots, Jews and Walloons, to name a few. In the 20th century, there were Asian, African and East European waves. I think that this has added to our culture no-end and as a result, has made the UK one of the most diverse countries in Europe.
