Smart to change the name. She might even alter her appearance a bit (hair and eye color, perhaps).

It could be that they Summerville is in California, and that the creatures are from different isolated islands in and around California (islands in the middle of lakes, for example, or mysterious islands off the coast). You could also say that there are a series of islands which appear to be mirages, only appearing at random times for short intervals, and are unfindable at any other time. That helps to explain why the islands can't be found - they just can't be seen most of the time.
