Gerberga married on 22 August 1036 to King Ramiro I of Aragon. After her wedding Gerberga changed her name to Ermesinda. The couple were married for thirteen years, in which time her husband elevated himself from a vassal holding scattered lands around Jaca into a de facto ruler of pocket-kingdom spanning the former counties of Aragon, Sobrarbe and Ribagorza, and is thereby credited with being the first King of Aragon. They had the following children:
- Sancho Ramírez (c. 1042 – 4 June 1094), succeeded his father
- García, Bishop of Jaca (d. 17 July 1086)
- Teresa (b. 1037), married William Bertrand of Provence, no issue
- Sancha (d. 1097), possibly married firstly to Pons, Count of Toulouse, and secondly to Ermengol III, Count of Urgell
- Urraca (d. 1077), a nun
All of Ermesinda's children lived to adulthood. She died on 1 December 1049 and she was buried at the Monastery of San Juan de la Peña. Her husband remarried four years later to Agnes.
