I remember a while back there was a discussion about character names, but I can't seem to find it.
I decided to do a search for missing persons which gave me a decent list, including under what conditions the person disappeared (Maybe a good for alien abduction story characters?).
Then I thought about victims of disasters
difficult to identify (I.E. a badly decomposed body, severely burned body, etc. One record I read had people being identified by a 'unique stitch used to mend a tear' and the way a shoe was buttoned).
not enough left to make positive ID (chemical/refinery explosion? 'I found a foot')
never found (sea disasters? how many never recovered from Titanic?)
Then there are the ones that are never claimed (unknowns who end up in a mass grave).
I figure as long as you don't used a recent disaster, the names can work, especially if the story is about a way the person 'could' have survived if an outside entity had taken them elsewhere/when.
