Theresa was born to two immigrant Sicilian parents, who Tom Hagen and the Corleone family would later help when they faced legal trouble to their being Italian non-citizens during World War II. Theresa met Tom Hagen and married him in the late 1930s. They never divorced, despite Tom's affair with Judy Buchanan, although they were known to have had near at least one break-up and tumultuous arguments over Tom's affair and his business life. She was particularly close to her informal sister-in-law, Sandra Corleone. She was a college graduate, intelligent, and articulate. She was an expert in art.
Theresa attended Vito Corleone's birthday dinner in 1941, as well as the wedding of Connie Corleone. When Tom was kidnapped by Virgil Sollozzo, Theresa stayed at the Corleone compound until his return. She had four children with him, two sons Frank and Andrew before some time before 1945, and two daughters, Christina in 1954 and Gianna in 1959.

In the 1960s, Theresa had became a noted art expert and helped found the Las Vegas Institute of Modern Art in the 1960's. When Judy Buchanan was murdered and Tom's affair was discovered, Theresa briefly moved away from him, taking their two daughters, who were not yet adults like their sons, with her to their home in Florida. The couple eventually reconciled and she accompanied Tom on his visit to the Woltz mansion.
After Tom's death, Theresa remained close to her husband's adoptive family. She continued to appear at family venues, visiting Michael Corleone, accompanied by her son Andrew, after Michael was given the Order of Saint Sebastian in 1979.
Personality and traitsEdit
A kind-hearted and gentle woman, Theresa rarely lost her temper, even when she discovered her husband's affair. However she never fully recovered from this experience and behaved bitterly towards Tom for sometime before ultimately forgiving him. She valued spending time with family, including Tom's adopted family, the Corleones, even after Tom's death.
