Catherine, Princess of Asturias
Catherine of Castile (Castilian: "Catalina de Castilla"; 5 October 1422 - 17 September 1424) was "suo jure" Princess of Asturias and heiress presumptive to the Castilian throne all her life.
Catherine was born on 5 October 1422 in Illescas, Toledo.
She was the first child of King John II of Castile and his first wife, Maria of Aragon.
Named after her aunt and grandmother, the Duchess of Villena and Catherine of Lancaster, she immediately became heiress presumptive to the throne of Castile upon her birth.
The Infanta was formally recognised as successor to the throne of the kingdom and sworn in as Princess of Asturias on 1 January 1423 by the Cortes of Toledo.
However, the Princess of Asturias did not live long enough to succeed her father as Queen of Castile.
She died in Madrigal de las Altas Torres on 17 September 1424.
Her younger sister, Infanta Eleanor, replaced her as heiress and Princess of Asturias.
Princess Catherine is buried in Miraflores Charterhouse, along with her father and stepmother, Isabella of Portugal.

María de las Mercedes, Princess of Asturias
María de las Mercedes, Princess of Asturias (María de las Mercedes de Borbón y Habsburgo-Lorena) (11 September 1880 – 17 October 1904), was the eldest child of King Alfonso XII of Spain and his second wife, Maria Christina of Austria.
She was Princess of Asturias, the heir presumptive to the Crown of Spain, for all 24 years of her life.
Had her younger sibling, unborn at the death of Alfonso XII, been a daughter, Mercedes would have been Queen of Spain.
The sibling proved to be a boy, Alfonso XIII, and on his birth in 1886, Mercedes turned out not to be queen.
She resumed the position of heir presumptive, which she held until her own death, and was succeeded in it by her own infant son Alfonso, Alfonso XIII having not yet married and fathered a legitimate child.
Mercedes married in Madrid on 14 February 1901, her second cousin, Prince Carlos of Bourbon-Two Sicilies, a nephew of the King of the then-defunct Kingdom of the Two Sicilies, who was elevated to the rank of Infante of Spain.
The marriage was highly controversial due to her father-in-law's ties with the Carlists.
She died three years later from complication while giving birth to her third child.
Infante Alfonso, Duke of Calabria
Infante Alfonso of Spain, Prince of the Two Sicilies, Duke of Calabria( 30 November 1901 – 3 February 1964) 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).
He was born and died in Madrid, Spain.
Alfonso's mother was Mercedes, 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.
He was heir- presumptive until the birth of his cousin, Alfonso in 1907, to Alfonso XIII and Queen Victoria Eugenie.
Princess Maria Christina of Saxony (1770–1851)

She was the Princess of Carignano and later Princess of Montléart by marriage.
Eleanor, Princess of Asturias
Eleanor of Castile (Castilian: "Leonor de Castilla"; 10 September 1423 - 22 August 1425) was heir presumptive to the throne of the Crown of Castile and Princess of Asturias from 1424 until a few months before her death.
Eleanor was born an infanta of Castile.
She was the second child of King John II of Castile and his first wife, Maria of Aragon.
Eleanor's elder sister, Catherine, Princess of Asturias, died seven days after Eleanor's first birthday.
Thus, the one-year-old infanta became heir presumptive to the throne.
Her father had her recognised as successor to the kingdom and as Princess of Asturias by the Cortes of Valladolid shortly after her sister's funeral.
The new Princess of Asturias received homage in the presence of her father, the King, in City of Burgos.
Princess Eleanor held this title and status for two months only.
On 5 January 1425, she was displaced by the birth of a brother, the future King Henry IV of Castile.
Now merely infanta and second-in-line to the throne again, Eleanor died the same year near the Cistercian monastery in La Espina.
She was buried there, near the altar.
