McKay's Harbour was named after Alexander McKay who operated a small fur trading post at Pays Plat and his son Charles McKay who was lighthouse keeper at nearby Battle Island, 1878-1913.
The name changed to Ross Port named after John Ross, construction manager for the north shore of Lake Superior route of the Canadian Pacific Railway from August 1882-June 1885. His construction headquarters during that time period were in Port Arthur, Ontario and at Rossport, then known as McKay's Harbour.
After the end of CPR construction in 1885, Rossport became an important commercial fishing centre. Bowman Street is named after John Bowman (1858–1950) who operated a fishing company here.
Rossport has remained a sport fishing center even after the devastation caused by the invading sea lamprey in the 1950's. http://en.wikipedia.org/wiki/Rossport,_Ontario This cache is a a small camo pill bottle.
