Maria married Antonio Scaletta in the small Sicilian village of San Martino, in 1920. Soon after, in 1921 their daughter Francesca was born, followed by their son Vito in 1925. The family moved to America sometime in 1932 for a better life, but instead Maria and her family were met with poverty and many hardships. She watched as her family started to fall down in front of her, with her husband drinking heavily, and then dying from drowning. She now lives with only her daughter and slowly waits for something good to come of her family. She continues to live in the same apartment that she, her husband and two children have lived in since they came to America. Her daughter continues to live with her and support both herself and her mother by taking a job at the Trago Oil Co.. Maria is a devoted Roman Catholic woman.

- The only time Vito cries in Mafia II is when he finds out that his mother died.
