Sandra Corleone (neé Colombo) was the wife of Sonny Corleone.
Biography
Sandra was born in Messina, Sicily, and was raised in The Bronx by her grandmother Anita. She married Sonny in 1935 after a long period of courtship chaperoned by her grandmother. Sandra was the mother of his four children, Francesca, Kathryn, Frank and Santino Jr. She was known to be well aware of her husband's womanizing, but took it in her stride.
She lived on the Corleone family Compound with her family until Sonny's death, when she and her family moved to Florida, having been financially assisted by the family.
