I also have an English-Scottish-Cuban connection. My maternal great great grandfather was Robert Waugh (b1831 Whickham, Durham, England), he was married to Alice McNicol (b1828 Kilbarchan, Renfrew, Scotland). Their families immigrated (1842) to, and married (1852) in New Orleans, Louisiana. Robert was an engineer and built, installed, and managed sugar cane mills in the Caribbean, but mostly in Cuba. He died in Cuba in 1877 as result of "crossfire" between Cuban rebels and Spanish troops as they were defending the sugar mill El Porvernir, outside of the town of Colon, in Matanzas province. Two of his daughters remained in Cuba and married Spaniards (our Cuban branch). Alice died, and is buried at the Valance Street Cemetery in New Orleans. Nineteenth century Spanish census of Cuba that I have reviewed show, after Americans, a large number of English and Scottish residents. Remember that the Cuban railroads during he second of the century were managed and owned by the Brits. Have you checked the Archives of the Foreign Office in London, to see if the death of your Mr. Buick was registered at the local British Consulate? Cuban records would not be easy to research. Good Luck. Jorge Pinon.
