Marianna was born on 8th November of Filippo Arborio di Gattinara Sartirana Breme and Marianna d’Hallot des Hayes.

In 1820 she married Marquess Carlo Emanuele Ferrero della Marmora to whom she gave eight children: Celestino who died as a baby in 1822, Vittorio (1828-1859), Guido (1830-1862), Emilia (1832-1874), Filippo (1834), Filippina (1837-1900), Albertina (1823-1890) and Tommaso (1826-1900) who was the only one to produce heirs. Marchioness Marianna was involved with the fate of the convent of San Sebastiano in Biella which, after the confiscation of the church endowments , had been turned into a warehouse and dormitory for soldiers. As a widow, in 1862 she asked Monseigneur Losana for the Holy Sacrament to be returned to the basilica and she herself paid the sacristan and the annual expenses of the church. She died in Turin in 1870 and was buried in the family tomb in San Sebastiano in Biella.
