Maria Theresa Isabel Eugenia Patricinio Diega Infanta of Spain was the second daughter of King Alfons XII. (1857-1885) and his second wife Maria Christina Archduchess of Austria (1858-1929). She was born on November 12th 1882 in Madrid and died there on September 23rd 1912. Maria Teresa married Ferdinand Prince of Bavaria (1884-1958) on January 12th 1906 in Madrid. Ferdinand renounced his rights to the Bavarian throne and was given the title "Infant of Spain" in 1914.
The couple had 4 children:
- Luís Alfonso (1906-1983)
- José Eugenio Alfonso (1909-1966)
- Maria de las Mercedes (1911-1953)
- Maria del Pilar (1912-1918)
The children were born as Princess / Prince of Bavaria. Later they were given the title "Infanta / Infant of Spain". Does anybody know if they had both titels then?
