In the United States, an almost extinct dialect of Dutch, Jersey Dutch, spoken by descendants of 17th-century Dutch settlers in Bergen and Passaic counties, was still spoken as late as 1921. Other Dutch-based creole languages once spoken in the Americas include Mohawk Dutch (in Albany, New York), Berbice (in Guyana), Skepi (in Essequibo, Guyana) and Negerhollands (in the United States Virgin Islands). Pennsylvania Dutch is not a member of the set of Dutch dialects and is less misleadingly called Pennsylvania German.

What's the year that Jersey Dutch was last spoken, according to records?
