Henry Ladd Corbett (1881-1957) and Hamilton Forbush Corbett (1888-1966) were the sons of Henry Jagger Corbett (1858-1895) and Helen Ladd Corbett (1859-1936); they were also the grandsons of Henry Winslow Corbett (1827-1903), an early emigrant to Portland, Oregon. When Henry W. Corbett died, Henry L. Corbett and Hamilton F. Corbett, along with their brother Elliott Ruggles Corbett (1884-1963), inherited the elder Corbett's wealth and businesses. All three brothers attended Harvard University in Cambridge, Massachusetts.

Hamilton F. Corbett served in a field artillery unit during World War I, and was wounded during fighting along the Ourcq River in the Second Battle of the Marne. He returned to the front in time for the Armistice, and served as aide-de-camp for Major General James Harbord with American occupation forces in Germany until his discharge in May 1919. Henry L. Corbett, meanwhile, was president of the Oregon Defense Council and Portland chair of the United States War Trade Board. He began training for military service, but the war ended before he was to be commissioned.

Following the war, all three Corbett brothers engaged in a number of businesses and real estate enterprises, including the Corbett Investment Company and the construction of the Pacific Building in Portland. Henry L. Corbett also became involved with local Republican politics, and served in the Oregon Senate, including as president of the Senate for the 1927 and 1935 legislative sessions. He unsuccessfully ran for governor of Oregon in 1930. He was also a commissioner for the Port of Portland from 1924 to 1951, and was its president for 13 years.

Hamilton F. Corbett married Harriet Cumming in 1922. Henry L. Corbett married Gretchen Hoyt in 1908, and the couple had five children: Helen; Henry Ladd, Jr.; Alfred Hoyt; Elliott Ruggles II; and Rosina. Henry L. Corbett died of a heart attack in April 1957 in Dunsmuir, California, while en route to Portland from Santa Barbara. Hamilton F. Corbett died in 1966 in Portland.

Howard V. Morgan was born in 1914 in Tillamook, Oregon, though his family then moved to Portland, Oregon. He attended Reed College in Portland, and in 1940 married Rosina Corbett (1919-2015), the youngest child of Henry L. Corbett and Gretchen Hoyt Corbett; the couple had four children.

Morgan served in the U.S. Navy Air Transport Service during World War II. In 1948, he was elected as a Democratic Oregon state representative.

Kennedy appointed Morgan to the Federal Power Commission; Morgan resigned from the commission in 1963, complaining that the board's majority favored private power companies over public utilities. He then ran a gravel and construction business in Portland, though he reentered politics in 1966 to run against Democratic incumbent Bob Duncan in Oregon's U.S. Senate primary, and co-chaired Eugene McCarthy's presidential campaign in Oregon in 1968.

After retiring in the 1970s, Morgan and his wife lived in Spain and then on a houseboat on Sauvie Island, Oregon, before moving to a ranch near McMinnville, Oregon. Morgan died in 2012 in McMinnville.
