According to Biography.com (the Website of the TV show Biography), Bartolomeo Vanzetti was born in the town of Villafalletto, Italy. See http://www.biography.com/search/article.jsp?aid=9468790&search= for the full article. (The American National Biography, published by Oxford University Press under their own auspices and those of the American Learned Societies confirms Villafalleto as the city of Vanzetti's birth. --jf) The GEOnet Names Server lists Villafalletto as being at 44° 33' 00" N latitude and 007° 32' 00" E longitude. The only sites with more information that I can find are Italian, so I don't know much about them. Several sites confirm that Villafalletto is a small town in the Piemonte Region, Cuneo Province. A a site called Piemonte Web shows a map with links to information about the modern town of Villafalletto.
Vanzetti's autobiography, The story of a proletarian life, published in 1923 by the Sacco-Vanzetti Defense Committee, should have more information about him. Numerous articles and books have been written about the Sacco-Vanzetti case. For articles, see Chobanian, P. "The Sacco-Vanzetti case: a bibliography of journal articles." Bulletin of Bibliography v. 44 (March 1987) p. 19-23. For books, try searching a library catalog for the subject "Vanzetti, Bartolomeo, 1888-1927."
