Prior to World War I, Caruso had been romantically linked to an Italian soprano, Ada Giachetti, who was a few years older than he was. Though already married, Giachetti bore Caruso four sons during their liaison, which lasted from 1897 to 1908. Two survived infancy: Rodolfo Caruso (1898-1951) and singer/actor Enrico Caruso, Jr. (1904-1987). Ada had left her husband, manufacturer Gino Botti, and an existing son to cohabit with the tenor.
