Quoting: The article Peterweg posted
''the invaders wiped out substantial numbers of the indigenous population, replacing 50 percent to 100 percent of those in central England.
Their argument is that the Y chromosomes of English men seem identical to those of people in Norway and the Friesland area of the Netherlands, two regions from which the invaders may have originated.''
Exactly my point.

I'm talking about the people you call English today, and not about the tribes which may have been there before them. So, if we're tracing everything back to the beginning, then we'd all come from one continent anyway..
But my point was, English as you speak it, definitely derives from a Germanic language. Also, the English language shows a huge Celtic and Normandic influence aswell.
Just compare Spanish and Portuguese to English, and then compare German and Dutch to English? (And the Fresian language really is a dialect here, it doesn't even sound like modern day Dutch.)
I'm not saying this theory about the first inhabitants of the British Isles can't be right, but I'll have to disagree with you when you state that modern day English doesn't originate from a Germanic language..
It's an interesting topic anway.
