Many people ascribe their own name to a particular place without regard to an actual name.
For instance, Blind Island, at the head of Blind Bay, was for years known to locals ar 'Fox Island' after the family that lived on that rock since the turn of the century. The 1900's, that is. I tried to call a 'Catherine Bryant' who lives on Orcas Island to determine if it is she that you are looking for. I left a message on her machine, hopefully she is not away for the winter and will respond quickly. I'll let you know.
