In 1791 Vincenza was dancing with Onorato Viganò's company in Venice when she met the recently widowed tenor Domenico Mombelli.
She continued her dancing career for some time after her marriage, appearing in the Teatro San Benedetto in Venice only a few months before the birth of her fourth child in 1798.
[1][2] Although primarily based in Bologna by 1805, the Mombelli family also travelled from 1806 to 1811 to Lisbon and various theatres in Italy with their own opera company which included their daughters Ester and Anna and the bass Lodovico Olivieri.
According to an account in Stendhal's Vie de Rossini, Olivieri was an old friend of Vincenza who not only sang "utility roles" in their company but also served as the family's cook and major domo.
It was in Bologna that Vincenza and Domenico made the acquaintance of the young Rossini who was still a student at the Accademia Filarmonica.
