Question: Which county was included in the Diocese of Reno and was also the county seat of Ormsby County prior to 1969?

Ormsby County, Nevada was a county of Nevada from 1861 until 1969.  It contained Carson City, the county seat, and later, the state capital, founded two years earlier.  It was named after Major William M. Ormsby, one of the original settlers of Carson City, killed along with seventy-five other white men in 1860, in an unsuccessful attempt to subdue a perceived uprising of Paiute Indians near Pyramid Lake, Nevada, which was at the time part of Utah Territory. <SEP> The Roman Catholic Diocese of Reno is an ecclesiastical territory (or diocese) of the Roman Catholic Church in the northern Nevada region of the United States, centered on the city of Reno.  The diocese comprises the counties of Carson City, Churchill, Douglas, Elko, Eureka, Humboldt, Lander, Lyon, Mineral, Pershing, Storey and Washoe.  The bishop of Reno has his liturgical and canonical seat ("cathedra") at The Cathedral of Saint Thomas Aquinas. <SEP> Carson City, officially the Consolidated Municipality of Carson City, is an independent city and the capital of the US state of Nevada, named after the mountain man Kit Carson.  As of the 2010 census, the population was 55,274.  The majority of the population of the town lives in Eagle Valley, on the eastern edge of the Carson Range, a branch of the Sierra Nevada, about 30 mi south of Reno.  The town originated as a stopover for California bound emigrants, but developed into a city with the Comstock Lode, a silver strike in the mountains to the northeast.  The city has served as the capital of Nevada since statehood in 1864 and for much of its history was a hub for the Virginia and Truckee Railroad, although the tracks were removed in the 1950s.  Prior to 1969, Carson City was the county seat of Ormsby County.  In 1969, the county was abolished, and its territory merged with Carson City to form the Consolidated Municipality of Carson City.  With the consolidation, the city limits today extend west across the Sierra Nevada to the California state line in the middle of Lake Tahoe.  Like other independent cities in the United States, it is treated as a county-equivalent for census purposes. <SEP> The Roman Catholic Diocese of Orlando (Latin: "Dioecesis Orlandensis" ) is a Roman Catholic diocese in Florida.  It was established on June 18, 1968.  Prior to that the Central Florida area was part of the Diocese of St. Augustine.  Today the diocese encompasses nine counties including Orange, Osceola, Seminole, Marion, Lake, Volusia, Brevard, Polk, and Sumter, a total of about 9611 mi2 .  William Borders, the first Bishop of the diocese, claimed in 1969 to Pope Paul VI that the then-active 1917 Code of Canon Law placed newly explored territory under the ecclesiastical jurisdiction of the port of departure, making the Diocese of Orlando responsible for the moon following the flight of Apollo 11.  If true, the total area of the diocese would be 14,657,051 mi2 , making it the largest Catholic diocese in existence.  In 2010, the diocese contained 81 parishes, 10 missions, and 37 schools.  St. James Cathedral serves as the seat of the diocese.  Within the diocese are two minor basilicas, Mary, Queen of the Universe Shrine, a basilica which ministers to Catholic tourists, and St. Paul's in Daytona Beach.
