Brambilla was born in Cassano d'Adda, the daughter of Gerolamo and Angela (née Columbo) Brambilla. She was the eldest of five sisters, all of whom became opera singers. Teresa (1813–1895) was a soprano who created the role of Gilda in Rigoletto. Giuseppina sang both contralto and soprano roles and was married to the tenor Corrado Miraglia. Both had very prominent careers. Annetta (1812–?) and Lauretta (1823–1881) were both sopranos who had lesser careers, appearing primarily in provincial Italian opera houses.Cernuschi, Angelo (2013).
