He was born in Madrid, the eldest son of Gregorio José de Toro and of his wife Josefa Dumont y Michel.
He fought with the Spanish Army against independence, and went into exile in Perú with the remains of the Royalist army after the defeat at the Battle of Chacabuco in 1817, while the pro-independence government confiscated all his properties.
He returned the next year with the army of Brigadier Mariano Osorio, of whom he had become personal adjuntant.
He was killed a few months later during the Battle of Maipu, and was in turn succeeded to the title by his sister, María Nicolasa.
