On a personal note...
My great-grandparents on my mother's side of the family were Isleños , or "islanders", from the Canary Islands. They emigrated to Cuba during the 18/19th century. I have even been told I speak Spanish with an Isleño accent, as do many other Cubans. It is my understanding the Spanish Crown encouraged emigration to Cuba from Las Islas Canarias because of economic troubles on the islands, and because of a shortage of white people in Cuba. (They were afraid of slave revolts, like in Haiti.)
I also understand that there is also a small remnant Creole Isleño colony in Louisiana. In the New World, we are all immigrants.
