Julien Dubuque, a French-Canadian who came to this area around 1785, gave his name to the city of Dubuque. After wooing Potosa, daughter of the Fox chief Peosta, whose village stood at the mouth of Catfish Creek, he received from the Fox Indians in 1788 the right to work the lead mines in what is now Dubuque County. In 1796 Governor Carondelet of Upper Louisiana granted him the first and largest of three Spanish Land Grants in Iowa, a 9-mile-wide tract called the Mines of Spain along the Mississippi between the Little Maquoketa and Tete de Mort Creek. Each fall he went to St. Louis with furs and lead, but his mining venture failed, and burdened by debt to Auguste Chouteau, he signed away the southern half of his grant. After his death in 1810, the Chouteaus tried to take over the land, but the Fox Indians drove them away, insisting he had only been given mining rights rather than ownership, a position the United States Supreme Court upheld in 1853. Nearby, the Trappist Abbey of Our Lady of New Melleray, established in 1849, traced its roots to a monastery founded at Citeaux, France, in 1098. Irish monks from the Abbey of Melleray in France founded Mount Melleray Abbey in Ireland in 1830, and the order later accepted Bishop Loras's invitation to establish New Melleray Monastery on 500 acres near Dubuque. Its original frame building was replaced by a two-wing Gothic-style monastery occupied in 1875 and completed after World War II, when membership grew rapidly. The Trappist monks followed an austere life of silence, labor, private prayer, and community worship, supported themselves through farming and stock raising on 3,200 acres, and two of their monks later became the second Bishop of Dubuque and the first Bishop of Omaha.
