That's slightly off - Alan is part Welsh, part Irish and part English. Sean Biggerstaff was Scottish. Richard Harris was Irish. Devon Murray is Irish. Robbie Coltrane is Scottish! And I was sure Maggie was Scottish too...(probably my mistake).. And yes before anyone says those countries are a part of the UK too!

I really don't like Hogwarts being referred to as English, it's situated in Scotland.

Meh, he probably wouldn't know that.

I even believe, or think, Rupert was born somewhere near or in Cornwall and people there considered themselves celts (like the Welsh, Irish and Scottish) too. They even have their own language!
