Fray Antonio Castilblanco was born circa 1499. A secondary source suggests that he was from the modern province of Córdoba. He arrived in New Spain in 1538. At forty-one he was one of the oldest participants on the Expedition. He was a Franciscan priest in Toluca, Mexico just prior to the departure of the Expedition. He broke his leg while on the Expedition, was sent back some distance to recover, and finally caught up with the main body of the expedition to continue on to Tiguex. He later served as a priest in Lima, Peru in the 1550s. By 1585 he was dead and had been buried in the large Franciscan convent in Mexico City.
