As these newcomers took on the position of the ruling-class, their language became the official tongue, and their practices of adopting surnames may have become de riguer, but the vast majority of the peasant population would have continued to be of Briton (rather than Germanic) descent. - Much the same thing happened in Central and Southern America - the Spanish Conquestadors brought the Spanish language and culture to Mexico and Latin America, but the population remained primarily that of the Native American tribes who are genetically closer to their Q-Haplotype Asian ancestors than they are to R1b Europeans.
Well most of the evidence actually shows that many, many Britons fled the island of Britain and established the colonies of Gailcia and Brittany - as well as moving to parts of Wales and Cornwall.
My main point was that Britons did not live throughout the island of Britain prior to invasions and after these invasions they were far less than a majority within the island.
