Shannon, Margaret Cather (1915-1996) (half of the “twinnies”). Cather’s niece. Margaret and her twin sister Elizabeth were born in Lander, WY, to Roscoe and Meta Cather, and moved with the family to Casper, WY, in 1921. Elizabeth and Margaret both attended the University of Colorado, graduating in 1937, and visited Willa Cather and Edith Lewis on Grand Manan during the summers of 1936 and 1937. In Cather’s later letters to them, she often refers back to their summer visits as a magical time. Margaret moved to Colusa, CA, with her parents in 1937. After she married Richard Shannon in September 1938, she moved with him to Boston, MA, where he earned an MBA from Harvard University in Cambridge. In 1940 they moved to the New York City area, where their first child, Richard, was born in 1943. The Shannons moved to Washington, DC, in 1944, where their daughter Kathryne was born. Cather did not see Margaret again after she left New York, and Margaret’s other three children, Patricia, Margaret, and Elizabeth, were born after Cather’s death. Kathryne and Patricia became caretakers for a large family archive of letters preserved by their mother, which they donated to the University of Nebraska-Lincoln as the Roscoe and Meta Cather Collection.

Lewis, Edith Labaree (1881-1972). Magazine editor, advertising copywriter, and Cather's domestic partner. Born in Lincoln, NE, to Henry Euclid Lewis and Lillie Gould Lewis, Edith Lewis attended the preparatory school associated with the University of Nebraska, earning college credits from the University before transferring to Smith College in Northampton, MA, in 1899. She received an A.B. in English from Smith in 1902 and returned home to teach elementary school. She met Willa Cather in the summer of 1903 at the home of Sarah Harris, publisher of the Lincoln Courier. Moving to New York City soon afterward, Lewis settled into a studio on Washington Square and found work at the Century Publishing Company. Cather was her guest when she visited the city from Pittsburgh. In 1906, at Cather's suggestion, Lewis applied for a position as an editorial proofreader at McClure's Magazine, and the two women worked together on the McClure's staff for six years. In 1908, they moved into a shared apartment at 82 Washington Place, and then, in 1912, to Five Bank Street. Lewis left McClure's in 1915 to become managing editor of Every Week Magazine, where she stayed until the magazine folded in 1918. In 1919 she began a long career as an advertising copywriter at the J. Walter Thompson Co. In 1926 Edith Lewis acquired the land on which she and Cather built their cottage on Grand Manan Island. When they lost their apartment on Bank Street to subway construction in 1927, they shared quarters at the Grosvenor Hotel when they were both in New York City. In 1932 they took an apartment at 570 Park Avenue. Throughout their relationship, Lewis was closely involved in Cather's creative process, reading and editing her work in pre-publication forms. Cather's will appointed Lewis as executor of her literary estate and a beneficiary of her literary trust. Lewis authorized E.K. Brown as Cather's first biographer and published her own memoir of Cather, Willa Cather Living (1953). She remained in their Park Avenue apartment after Cather's death and died there after a long period of illness and invalidism. She is buried at Cather's side in Jaffrey, NH.

Brockway, Virginia Cather (1912-1984) (“West Virginia”). Cather's niece. Born in Lander, WY, to Roscoe Cather and Meta Schaper Cather, Virginia graduated from Natrona County High School in Casper, WY, in 1929. She received an A.B. in English from Smith College in Northampton, MA, in 1933, the same year Willa Cather received an honorary doctorate there. In 1934, she enrolled in the University of Chicago School of Social Services and was, for a time, a social worker. She married John Hadley Brockway, a Navy officer, in 1936. They moved frequently until his retirement from the Navy. She had one child, son George. In letters, Willa Cather sometimes calls her "West Virginia" to distinguish her from her cousin Mary Virginia Auld because Virginia Cather's birthplace in Wyoming was farther west than Mary Virginia's in Nebraska.
