• Toledo Beach is a former community located along the shores of Lake Erie just south of North Shores. It was settled as a summer resort and also had a station along the Toledo, O.B. & N. Railroad. Previously, the area was called the Ottawa Beach Resort until it was purchased by the Toledo Rail Light and Power Company, and the 400-acre (1.62 km) Toledo Beach Amusement Park was built in 1907. A post office began operating on May 29, 1915. The amusement park prospered and was accessible by a trolley line from Toledo, Ohio. The line ran through several lakefront communities leading to Toledo Beach until the line was shut down in 1927. By 1950, the park contained many attractions, a dance hall, train rides, and numerous other amenities. Financial hardships forced the closure and selling of the park, in which it was demolished and replaced with the Toledo Beach Marina in 1962.
• Winchester is a former settlement located in the township at the mouth of Otter Creek at Lake Erie. It may have been named after James Winchester, who was a general whose militia protected the area during the War of 1812.
