Which country/countries could you represent

[Eric the Half a Bee]

On another thread Sean Morrison's eligibility to play for the Republic of Ireland was discussed.

If you were good enough, which country/countries would you be eligible to represent ?

As the rule stands I could only play for Wales. If it went back to my great grandparents, which it doesn't, I could play for the Republic of Ireland (on both sides of the family).

Wales.

My dad could have played for Wales or England. My mum could have played for Wales, England or Norway.
