Can anyone claim to be 100% english? My genetic make up is scottish, notrhern irish, irish, english, and god only knows what else

Even Her Majesty, The Queen of England and her Dominions etc etc, can hardly claim to be english. Me thinks there may be a bit of ger men blud in her.. Is there a way to get rid of the rong bits of blud.

I was told that i was made in the likeness of god and am descended from Adam and whatever Eve was up to, which puts a bit of Palestinian blud in me as well, and wat nationaity was god ?
