In July 1832, she appeared as the heroine in
Adelina by
Pietro Generali at Milan's
Teatro della Canobbiana; this was apparently her operatic debut. During this time, her old singing teacher, Andrea Costa, sued her for 50% of her operatic earnings, based on the contracts that her parents and husband had signed. In Paris, in November 1839, she gave birth to her second daughter, Marianna Emma Clotilde Lucrecia Albertazzi. She soon returned for a summer concert tour of Europe and Britain. At the end of 1840, she rejoined the
Théâtre des Italiens and followed the season with touring in Europe, avoiding London where the Costa case continued in the courts and the press. In 1841–1842, along with her operatic roles, Albertazzi continued to sing in may concerts, including in the première of
Rossini's Stabat Mater. She then gave concert tours in Italy and France, and gave birth to a third daughter, Fanny. In May 1843 she appeared as Adina in ''L'elisir d'amore'' at the
Princess's Theatre in London, where she appeared in other roles that season, also singing in concerts in England. In January 1845, her fourth daughter, Emma Victorine Sarah Violet Albertazzi, was born. Albertazzi again earned warm reviews for her concert work during the 1845 season. After two seasons away from the operatic stage, she returned in June 1846, singing several roles at the
Surrey Theatre. From October 1846, for the world premiere of
Loder's opera
The Wilis, or The Night Dancers, she sang the role of Giselle. She withdrew by January 1847 and gave birth to her fifth daughter, Sarah Henrietta Mary Albertazzi. She returned to the concert stage shortly thereafter, performing until March. Albertazzi became ill that spring and died from
tuberculous meningitis in September at her home in
St John's Wood, London, at the age of 32. ==Reputation==
