strayling

noun

1. A little waif or stray; a driftling.

   “[…] yet, seeing it in its true light, manages to hold herself aloof from it; unconsciously conveying to one meeting her for the first time the impression that she was in San Pasqual on her own sufferance—a sort of strayling from another world who had picked upon the lonely little desert town as the scene of her sphere of action for something of the same reason that prompts other people to collect postage stamps or rare butterflies.”
