Justo Boneo y Morales, governor of Texas and knight of the Order of Santiago, was born in Puerto de Santa María, Cádiz, Spain on August 17, 1695. He held the rank of lieutenant colonel in the Spanish army. He was ordered on July 15, 1740, to investigate the French boundary near Los Adaes and the charges made by Carlos Franquis de Lugo against former governor Manuel de Sandoval and the missionaries in Texas. Boneo y Morales was at Nuestra Señora del Pilar de los Adaes Presidio on December 17, 1743, when he assumed the office of governor of Texas. He had been appointed by the king himself. He attended the funeral of Louis Juchereau de St. Denis in June 1744 and thanked God that the irritating Frenchman was gone. Boneo y Morales died in September of the same year, while still in office.
