Question: Which American politician and women's rights advocate owned a home in Broadwater County, Montana?
Context: Lombard is a ghost town in southeastern Broadwater County, Montana, United States.  The town was located on the east bank of the Missouri River, just north of the mouth of Sixteen Mile Creek.  Lombard was established in 1895 as the western terminus of the Montana Railroad, and the location of its interchange with the Northern Pacific Railway.  In 1908, the Montana Railroad was incorporated into the new transcontinental main line of the Chicago, Milwaukee, St. Paul and Pacific Railroad ("the Milwaukee Road").  This lessened Lombard's importance as a railroad operational base, but the town survived as an interchange point between the Milwaukee and the Northern Pacific. Yorks Islands, also known as "Yorks 8 Islands" or "York's Islands" or simply "York Island(s)" are a group of several islands located in the flood plain of the Missouri River, in Broadwater County, Montana, about 4 miles south (up-river) from Townsend, Montana, along U.S. Highway 287.  The islands were named by the Lewis and Clark Expedition (1803–1806) for Clark's servant/slave York, when the expedition passed this way in 1805 on their historic journey of exploration to the Pacific Ocean.  The islands may be accessed from U.S.287, as a Montana Fishing Access site. Broadwater County is a county in the U.S. state of Montana.  As of the 2010 census, the population was 5,612.  Its county seat is Townsend.  The county was named for Charles Arthur Broadwater, a noted Montana railroad, real estate, and banking magnate. The Limestone Hills, el.  4977 ft , is a sub-range of the Big Belt Mountains southwest of Townsend, Montana in Broadwater County, Montana. Jeannette Pickering Rankin (June 11, 1880 – May 18, 1973) was an American politician and women's rights advocate, and the first woman to hold national office in the United States.  She was elected to the U.S. House of Representatives by the state of Montana in 1916, and again in 1940.  She is to date the only woman elected to Congress from Montana. Canton was a small town in Broadwater County, Montana, now submerged beneath Canyon Ferry Lake near Helena, Montana.  The town was flooded when nearby Canyon Ferry Dam, originally built in 1898 to provide electricity for Helena, was replaced by a second, larger dam which began construction in 1949.  When this was completed in 1953 the reservoir increased in volume by 50 times and eventually claimed 25 miles of river bottom, the town of Canton and 4,000 acres of farmland.  The Canyon Ferry Dam is currently owned and operated by the Bureau of Reclamation. The Rankin Ranch is a historic ranch off Montana Highway 284, north of Townsend in rural Broadwater County, Montana.  A National Historic Landmark, it was a longtime summer residence of Jeannette Rankin (1880-1973), whose 1916 election to the United States House of Representatives made her the first woman elected to the House.  Her legacy includes a penchant for pacifism, women's rights, and social reform.  She served another term from 1941-1943 when she was the only member of the House to oppose the declaration of war against Japan in 1941.  A small portion of the ranch was designated a National Historic Landmark and listed on the National Register of Historic Places in 1976. Townsend is a city in and the county seat of Broadwater County, Montana, United States.  The population was 1,878 at the 2010 census. Confederate Gulch is a steeply incised valley on the west facing slopes of the Big Belt Mountains in the U.S. state of Montana.  Its small stream drains westward into Canyon Ferry Lake, on the upper Missouri River Valley near present-day Townsend, Montana.  In 1864 Confederate soldiers on parole from the American Civil War made a minor gold discovery in the gulch, but in 1865 the discovery of the sensationally rich Montana Bar—one of the richest placer strikes per acre ever made—led to other rich gold strikes up and down the gulch, and touched off a frantic boom period of placer gold mining that extended through 1869.  From 1866 to 1869 the gulch equaled or outstripped all other Montana Territory mining camps in gold production, producing an estimated $19 to $30 million in gold—late 1860s money.  For a time, the gulch became the largest community in Montana—in 1866 Montana had a total population of 28,000, and of these, about 10,000 (35%) were working in Confederate Gulch.  The main community was Diamond City , and while gold production was at its height, Diamond City roared along both night and day.  During its heyday, Diamond City was the county seat of Montana's Meagher County, although today the area has become part of Broadwater County.  In their frantic efforts to get at more gold, the miners built ditches and flumes that extended for miles, and employed high pressure hydraulic mining methods which washed down whole hillsides and ate up the gulch floor.  The hydraulic mining process stripped the gulch and left huge spoil banks—hydraulic mining even consumed the site of Diamond City, which had to be moved to a new location.  Then the gold ran out, the boom was over and the population simply picked up and left.  In 1870 there were only 255 people left and a year later only about 60.  Today hardly a trace remains of Diamond City or the other gulch communities.  The gulch is quiet and empty, with only an occasional summer prospector, or a rare traveler using the unimproved road that still winds up the gulch from the Missouri Valley and crosses the top of the Big Belts on its way down to the Smith River Valley.  Diamond City, Confederate Gulch and the Montana Bar were spectacular examples of the flash-in-the pan Montana placer gold mining camps, but what a flash. USS "Broadwater" (APA-139) was a "Haskell"-class attack transport built for the United States Navy during World War II.  Named for Broadwater County, Montana, she was the only U.S. Naval vessel to bear the name.
