Juan Agustín Morfi, missionary, teacher, and historian, was born in the province of Asturias, Spain. He moved to America in 1755 or 1756 and became a Franciscan friar on May 3, 1761, at Mexico City. Noted for his learning and for his ability as a sacred orator, he taught theology at the Old College of Santa Cruz de Tlaltelolco and was later a lecturer on sacred theology at the principal monastery of the Franciscans in Mexico. When Teodoro de Croix came to New Spain in December 1776 as the newly appointed commandant general of the Provincias Internas, he decided to make an inspection tour and requested a friar to accompany him as chaplain. Morfi was recommended and accepted the position. On August 4, 1777, the group began the tour that eventually extended through Mexico, Tula, Querétaro, San Miguel de Grande, Zacatecas, Fresnillo, Sombrerete, Durango, Mapimí, Parras, Saltillo, Monclova, San Juan Bautista, and San Antonio de Béxar, then back to Mexico through Chihuahua. On the border between Chihuahua and Coahuila, Morfi must have been separated from the group, for his diary ends abruptly at Las Cruces on February 24, 1778. By March 31, 1778, he was back in Mexico. After his return, he devoted himself to study and writing. In 1782 he was elected guardián of the Convento Grande de San Francisco. He died on October 20, 1783. He is known chiefly for the history of Texas that he compiled after his long and arduous journey.
