Mistral was born in Vicuña, Chile, but was raised in the small Andean village of Montegrande, where she attended a primary school taught by her older sister, Emelina Molina. She respected her sister greatly, despite the many financial problems that Emelina brought her in later years. Her father, Juan Gerónimo Godoy Villanueva, was also a schoolteacher. He abandoned the family before she was three years old, and died, alone since estranged from the family, in 1911. Throughout her early years she was never far from poverty. By age fifteen, she was supporting herself and her mother, Petronila Alcayaga, a seamstress, by working as a teacher's aide in the seaside town of Compañia Baja, near La Serena, Chile.
