Off the top of my head, no. This sort of detective work can be fun, but it does take a lot of time to look at all the possibilities. And like as not you end up with too many or none at all. But when you're looking for an unaccompanied teenage girl who looks and sounds English (at least to an American) the best place to look is among the Irish. Don't take the assumed age too seriously. That's something which can be very hard to judge, especially with young people who grow and mature at different rates. A 12-year old could look 15, as could a 20 year old.
