Most immortals have an odd tendency to be from Europe.
In fiction a large amount of character who are supposed to be unusually long lived and immortal characters who now inhibit American have a tendency to come from Europe. At first glance this would seem make sense since America is generally regarded as a land built by migrants. However in some cases the characters are still 'young' enough to have been born and raised in America... which would have spared the audience many bad attempts at accents. This may be explained by the large number of inhibitants of America who acknowledge themselves as being descended from some region of Europe, which they may unthinking see as almost mystical. Of course it could also be some bizzare form of wish fullfillment for them that someone who knew their great great grandmother in their early twenties would still be alive and kicking. Ofcourse in more recent works it could be related to the fact that the various European races are the most reasonable ones to explain a lot of the prominent features in the appearance of American actors. Not to mention the fact that the countries in question are the cultures that American concepts are based off, which makes for both an easy handwave solution and makes it seem more probably they could stay hidden. Of course it doesn't really count as this if the setting for the story is in a Europe country. This is more about the general prevalance of immortal characters from them when characters from virtually any continent would make about as much, if not more sense.
