She married Manuel Murguía, a member of the important literary group known as the Royal Galician Academy, historian, journalist and editor of Rosalía's books. The couple had seven children: Alexandra (1859–1937), Aura (1868–1942), twins Gala (1871–1964) and Ovidio (1871–1900), Amara (1873–1921), Adriano (1875–1876) and Valentina (stillborn, 1877). Only two of Rosalía's children married, Aura in 1897 and Gala in 1922; neither they nor their siblings left any children, and thus, today there are no living descendants of Rosalía de Castro and her husband. Their son Ovidio was a promising painter, his career cut short by early death.
