I do not see the names Henry and William Alexander in my BLACKBURN family lineage, however, in a letter my Grandfather wrote to me he states that another branch of his Liverpool, England lineage went to the Caribbean. Have you tried the Caribbean list, CARIBBEAN-L@rootsweb.com? I have found it very helpful. My ggrandmother, Edith BLACKBURN, married Henry Archibald SMITH, 1867, in Antigua, where her father, William Joseph BLACKBURN, was a superintendent for Fawcett Preston, an English company that manufactured equipment to process sugar cane.
