I've found a few cases in the locations that also could use clarification, especially where names have been doubled up. I'm including lat/long to help out whoever may take on fixing this issue.
I may add more in additional posts if I find them, but for now I have:
Toledo, United States (41.7, -83.46) - Should be Toledo (Ohio), United States
Toledo, United States (44.6142, -123.94) - Should be Toledo (Oregon), United States
Rockport, United States (37.8908, -87.0455) - Should be Rockport (Indiana), United States
Rockport, United States (44.1834, -69.0727) - Should be Rockport (Maine), United States
The following aren't doubled-up, but I recommend modification to match common usage:
Channel Islands, United States - Channel Islands Harbor, United States
Judith Point, United States - Point Judith, United States
