The Stimpson Family Papers document different generations of the Stimpson and Watts families and their activities and achievements in the Pacific Northwest. Members of both families made significant contributions to the community of Bellingham, Washington, during the twentieth century, notably in the areas of health care, education, and business.

Born in Northampton, England, Edward W. Stimpson (1875-1960) emigrated to the United States with his parents, John and Caroline (Whitmell) Stimpson, as an infant. The family lived in Chicago, western Minnesota, and North Dakota before settling finally in the Pacific Northwest. Edward W. Stimpson returned to the Midwest to attend medical school at the University of Minnesota where he earned his degree in 1903. After graduation, Edward returned to the region and established his first medical practice in Roslyn, Washington. In 1905, he married Mabel Keown, with whom he had two children, Edward K. (Edward Keown) and Mabel.  In 1909, following his first wife's death, Edward married his sister-in-law, Edith Keown. Together, Edward, Edith and the children migrated to Bellingham, Washington in 1914, where he resumed his career as a physician.  In 1938, Edward married his third wife Ella Harrison. Edward W. Stimpson died in Bellingham in 1960.

Arthur E. Watts, his wife Maud Belden Watts, and their young daughter Ruth, moved to Bellingham, Washington from Nashua, Iowa around 1905. After arriving in Bellingham, the Watts family grew to include three additional children, Catharine C. (Kitty), Elizabeth (Betty), and Arthur Jr.  Arthur Watts Sr. began his career in Bellingham as a land agent for the Bellingham Bay Improvement Company, and later ran his own real estate and insurance business. Actively involved in civic affairs, Arthur was a founder and the first president of the influential Young Men's Commercial Club. Under Watts’ leadership, the club provided the funding to create Whatcom Falls Park in 1908. Arthur Watts Sr. died in 1930, and Maud died in 1950.
