On May 22, 1849, Maj. William Williams visited Burlington, writing a brief description in his journal:[12]

The City of Orange is a township in Essex County, New Jersey, United States. As of the 2010 United States Census, the township's population was 30,134, reflecting a decline of 2,734 (-8.3%) from the 32,868 counted in the 2000 Census, which had in turn increased by 2,943 (+9.8%) from the 29,925 counted in the 1990 Census.

Archaeological records indicate the presence of Aboriginal people in the Vancouver area from 8,000 to 10,000 years ago. The city is located in the traditional territories of the Squamish, Musqueam, and Tseil-Waututh (Burrard) peoples of the Coast Salish group. They had villages in various parts of present-day Vancouver, such as Stanley Park, False Creek, Kitsilano, Point Grey and near the mouth of the Fraser River.

"As to Brockton, MA -- I did find a reference to a letter SLC wrote to Pond complaining that the Brockton venue had not been advertised sufficiently, and thus had a low turn out."

Whatcom is the original name for the city of Bellingham. The name of Bellingham is derived from the bay on which the city is situated. George Vancouver, who visited the area in June 1792, named the bay for Sir William Bellingham, the controller of the storekeeper's account of the Royal Navy. Prior to Euro-American settlement, this was in the homeland of Coast Salish peoples of the Lummi and neighboring tribes. The first Caucasian settlers reached the area in 1854. In 1858, the Fraser Canyon Gold Rush caused thousands of miners, storekeepers, and scalawags to head north from California.

The land on which Everett was founded was surrendered to the United States by its original inhabitants under the 1855 Treaty of Point Elliott. Permanent settlement in the area by European descendants started in 1861 when Dennis Brigham built a cabin on a 160-acre claim on the shore of Port Gardner Bay. Over the next several years a handful of settlers moved to the area, but it wasn't until 1890 that plans for platting a town were conceived.

The area now called Ballard was settled by the Dxʷdəwʔabš (Duwamish) Tribe after the last glacial period[4][circular reference].[5] There were plentiful salmon and clams in the region.[6] The U.S.

The site of Olympia has been home to Lushootseed-speaking peoples for thousands of years, including Squaxin, Nisqually, Puyallup, Chehalis, Suquamish, and Duwamish. The first recorded visit by Europeans was in 1792 when Peter Puget and a crew from the British Vancouver Expedition charted the site. In 1846, Edmund Sylvester and Levi Smith jointly claimed the land that now comprises downtown Olympia. In 1851, the U.S. Congress established the Customs District of Puget Sound for Washington Territory and Olympia became the home of the customs house.

Winnipeg lies at the confluence of the Assiniboine and the Red River of the North, a location now known as "The Forks". This point was at the crossroads of canoe routes travelled by First Nations before European contact. Winnipeg is named after nearby Lake Winnipeg; the name is a transcription of the Western Cree words for muddy or brackish water. Evidence provided by archaeology, petroglyphs, rock art and oral history indicates that native peoples used the area in prehistoric times for camping, harvesting, hunting, tool making, fishing, trading and, farther north, for agriculture.

This area had long been inhabited by indigenous peoples. After the American Revolutionary War, the United States mounted the Northwest Indian War to push Native American peoples out of what it then called the Northwest - the area of the Midwest south of the Great Lakes and west of the Appalachian Mountains.
