The sentimental knot of Doña Rosita belongs to a love story starring a cousin of the author, Clotilde García Picossi. This woman identified with the character, revealing her secret over time: her boyfriend, a first cousin, went to the Argentine Tucumán and there married another; she waited for him for a long time.

Federico was always very close to his cousin Clotilde who spent much of the year in her Huerta del Tamarit (Tamarit Farmhouse), near the Huerta de San Vicente (San Vicente Farmhouse), in the fertile plain of Granada, summer residence of the García Lorca family. Also included in this story are the memories of the times of his mother, or of other single women known to him, such as his friend Emilia Llanos.
