• Infante Alfonso, Duke of Calabria (30 November 1901, Madrid, Spain[1] – 3 February 1964, Madrid, Spain[1]%29 was one of two claimants to the title of the head of the House of Bourbon-Two Sicilies from 1960 until his death in 1964. Alfonso was the son of Prince Carlos of Bourbon-Two Sicilies (1870–1949) and his wife Mercedes, Princess of Asturias (1880–1904).[1]
• Alfonso's mother was Princess of Asturias, but she died in childbirth in 1904. King Alfonso XIII of Spain was unmarried at the time so as the Princess of the Asturias' eldest son, Alfonso became heir-presumptive to the Spanish crown, though, unlike his mother, he never held the title of Prince of Asturias.[2] He was heir-presumptive until the birth of his cousin, Alfonso, to Alfonso XIII and Queen Victoria Eugenie.
