She married Ignacio Quintanilla.

In 1807, she sold Camargo 30 to Pedro Ygnacio Garcia for 75 pesos. Sold by Maria Rosalia Garcia on behalf of her mother Maria Antonia Salinas, wife of original grantee Ignacio Quintanilla (Rosalia Garcia was adopted, or mother also had been married to a Garcia?) Camargo Protocolos, p. 400. Pedro Ignacio Garcia described as "comercio". This tract sold for 50% more than the other porciones in the area, and seems to have had more land, perhaps due to its location at the bend in the river named "El Salto"
