Ok, so I am a little into research
The Havanese in the United States today are direct descendants from one of the Bichon groups originating in the Mediterranean area. There are several distinct groups of Bichon, including the Bichon Maltiase (Maltese), the Bichon Bolognese (Bolognese), the Bichon Havanais (Havanese), the Lowchen, the Coton de Tulear, and and the Bichon Teneriffe (Bichon Frise).
Some authorities differ as to the origin of this small breed. Fiorenzo Fiorone, when writing the book 308 Recognized Breeds, states that the Havanese is a descendant of the Italian Bolognese, which were taken by the Italians to Argentina, and there crossed with a small South American Poodle, creating a new member of the Bichon family. The hypothesis advanced by Dechambre is different. He believes the Havanese is descended from the Maltese, brought to the West Indies by the Spaniards, and were at that time called "The Havana Silk Dog".
