This sounds like the area I was asking about. An old family story says that when Gr. Grandma LAPONSA was a teenager her mother sent her across to an island to get her Dad from a tavern (or something of the sort) while her mother waited on the other side with a lantern. This would have been about 1900. No one really knew where they were from. They only knew "The Flats," and thought somewhere around New Baltimore. Do you know if the book you referred to would be available at a library?
