Dunne was a legal counsel involved in the Disston Land Purchase of 1881, and as his commission, received 100,000 choice acres (400 km2) of land out of the 4,000,000 acre (16,000 km2) purchase. The following year on February 15, while surveying the Disston Purchase with his cousin, Captain Hugh Dunne,[8] Dunne selected the area around Lake Jovita, which he named after St. Jovita, as his commission and began settling it.
He first established the Catholic colony of San Antonio in 1882, and later added the surrounding villages of Saint Joseph, Saint Thomas, Villa Maria, Carmel, and San Felipe. Only the rural community of Saint Joseph survives today.
The area of what is now the Town of St. Leo, although originally platted as another village by Dunne, did not receive its name until after the arrival of the Benedictine monks.[9] The present name is derived from Pope Leo IX.[10]

St. Leo contains rolling hills with elevations from 100 ft to 180 ft.
