In January 1836, Maria Isabella served as a godmother to her grandson
Francesco, Duke of Calabria. In March that same year, the Prince of Capua contracted a
morganatic marriage. Maria Isabella pleaded for her favorite son, but her efforts to obtain a pardon for him proved fruitless. Ferdinand II did not forgive his runaway brother: Capua went into permanent exile in England, and Maria Isabella never saw him again. As Maria Isabella was determined to remarry, her son, King Ferdinand II, gave her a list with names of young noblemen of the kingdom, from whom to choose. Her first two choices hesitated and she withdrew her proposals. Ultimately she selected Francesco, Count dal
Balzo dei Duchi di
Presenzano (1805–1882), a handsome young lieutenant from an ancient but impoverished noble family. Their marriage took place privately on 15 January 1839. She was 50 years old and the groom, 34. The couple had no children. They retired from the Neapolitan court, moving to the
Palace of Capodimonte. Tragedy struck the Queen Dowager when in January 1843,
Antonio, Count of Lecce, her fourth son was killed. Her fifth son,
Luigi, Count of Aquila, followed a career in the navy. In July 1843 he went to
Brazil when
Teresa, Maria Isabella's youngest daughter, married Emperor
Pedro II of Brazil. In 1845, to keep the Spanish throne in the
House of Bourbon Louis Philippe d'Orléans, King of the French, launched the idea of marrying Maria Isabella's youngest son
Francesco, Count of Trapani, who had been originally destined for the church, to Queen
Isabella II of Spain, her granddaughter, in another union between uncle and niece. The project did not, however, come to fruition. In the political crisis of late 1847, Maria Isabella, her son
Leopold, Count of Syracuse and her brother-in-law,
Leopold, Prince of Salerno, advocated in vain in favor of liberal reforms. Due to her affable character and generosity towards the poor, Maria Isabella remained a popular figure till the end. She died on 13 September 1848 at age 59. ==Issue==
