1) They live in England and identify as English.
2) They were born in England and identify as English.
3) They were born of one English parent.
4) They were born of two English parents.
5) They can trace back an unbroken pure bred line of "English" ancestors to 927AD.
6) Some other definition.
But you will refuse to answer because either this is a childish question, or more likely, you are full of shit.
