Tina Kay is originally from Lithuania, but is now resident in the UK.
Natalia Forrest was born in the Philippines, but was brought up in the UK since she was a small ***** (American father, Philippino mother apparently).
Jasmine Andreas is an Edinburgh lass (until recently my home city) with a distinct Scottish accent, despite the rather exotic name resulting from mixed ancestry (Greek and Indian as far a I'm aware).
The others mentioned are from various parts of England as far as I know
