Saint-Domingue
From TLP
Saint-Domingue is the name given to the French portion of Hispaniola prior to 1804. Among its spelling variations in various reference works are St. Domingue, San-Domingue, Santo Domingo and St. Domingo. After the Haitian revolution, upon declaring independence on January 1, 1804, the former French colony was renamed Haïti, the name originally used by the natives of the island. Saint-Domingue sometimes refers to the whole island of Hispaniola.
In the past U.S. and British authors often referred to Saint-Domingue as "St. Domingo" or "San Domingo," which may then be confused which what is today the Dominican Republic.
