Coulby Park is part of the original Coulby estate called Coulallenby and honors Wickliffe citizens Harry and May Allen Coulby. Harry C. Coulby (1865–1929), known as Czar of the “Great Lakes,” was a partner in a shipping company with a fleet of ore boats on Lake Erie and was the first elected mayor of Wickliffe, serving from 1916–1921. His wife, May Allen Coulby, founded the Wickliffe Well Baby Dispensary.
