McClure, Samuel Sidney (1857-1949) (“S.S.”). Irish-born American publisher. McClure immigrated to the U.S. at age nine, living with his family in Indiana. Despite poverty and the limited education he had received in Ireland, he graduated from high school and then Knox College in Illinois. He then moved to Boston, MA, where from 1882 to 1884 he edited the Wheelman, a bicycling magazine. Despite opposition from her parents, he married his Knox College classmate Harriet Hurd in 1883. The couple had four biological children (Eleanor, Bess, Mary, and Robert), and adopted one (Enrico). In 1884, S.S. started McClure’s Syndicate, which placed fiction in newspapers across the country. In 1893 with his college classmate John Sanborn Phillips he started McClure's Magazine, which was best-known for the "muckraking" exposés by writers such as Ida Tarbell and Lincoln Steffens, but which also published literature. After his cousin H.H. McClure, who worked for the McClure Syndicate, brought Cather to S.S. McClure’s attention, McClure, Phillips & Co. brought out Cather’s first book of fiction, The Troll Garden (1905). When most of the editorial staff, including Steffens and Tarbell, resigned from McClure’s in 1906, he hired Cather as an editor; she later became managing editor. After she left her position at McClure’s in 1912 and when S. S. McClure had lost control of the magazine still bearing his name, Cather ghost wrote his autobiography (McClure’s serial 1913-1914, book publication 1914). McClure made repeated—and ultimately failed—attempts to reestablish himself in journalism and magazine publishing, often trying to enlist Cather in these enterprises. She almost went with him to Europe in 1915 to report on the war for the Evening Mail, and she remained personally loyal to her mercurial and often-irresponsible former employer. He served as the prototype for Marcus O’Mally, editor of the Outcry, in her story “Ardessa” (1918), and it has been suggested that Cather modeled the courtship and marriage between Myra and Oswald Henshaw in My Mortal Enemy (1926) on that of the McClures.

Goudy, Alice Estelle Dailey (1853-1937). Cather’s high school teacher and friend. Alice Dailey grew up in Nemaha County, NE, where she attended the Nebraska State Normal School at Peru, NE, which her father had helped found. She married fellow teacher Alexander K. Goudy in 1882; both taught at the Normal School. When they moved to Red Cloud, NE, in 1888, he was superintendent of schools and she was the high school principal. She encouraged Cather to attend the University of Nebraska. The Goudys moved to Lincoln, NE, in 1891, when he was elected state superintendent of schools; Alice Goudy was assistant, then deputy, state superintendent. After A.K. Goudy suffered a stroke around 1900, the couple retired to Nemaha County. Cather wrote to Mrs. Goudy for many years, although few letters have survived.

Mellen, Mary Virginia Auld (1906-1982) (“Virginia,” “M.V.”). Cather's niece. Born in Red Cloud, NE, to Jessica Cather Auld and James William Auld, Mary Virginia graduated from Red Cloud High School in 1924 and then spent a year at Dana Hall in Wellesley, MA, to qualify for admission to Smith College in Northampton, MA. In 1929 she received an A.B. in psychology from Smith and then moved to New York City, where she found work at Lord & Taylor before telling her aunt of her arrival. In 1930, probably with Willa Cather's help, she secured a position in the Circulation Department of the New York Public Library. In 1931, she entered the library's internal training school and in 1932 was assigned to the Tremont branch library in the Bronx. After Mary Virginia’s parents divorced in 1933 Cather took a quasi-parental role. She paid for vacations and when, in 1935, Mary Virginia married Richard (Dick) Mellen, a graduate of Harvard Medical School and roommate of her brother William Thomas Auld at Amherst College, she supervised wedding arrangements. After Dick was commissioned as a doctor in the Air Force, Mary Virginia—much to Cather’s regret—accompanied him to Chattanooga, TN, where he was assigned. In Cather's will, Mary Virginia was designated a beneficiary of the literary estate.

Seymour, Elizabeth (c. 1859-1934) (“Bess,” “Bessie”). Cather’s cousin. Bess Seymour was born in Virginia to Sarah Boak (the elder sister of Willa Cather’s mother) and her first husband, Joseph D. Seymour. In 1883, Bess moved with Willa Cather’s family to Webster County, NE. Seymour lived in the Cather family home from 1883 to 1904, when she moved to the Webster County farm of her half brother, Will Andrews. Cather used her cousin’s name as a byline for the story “The Burglar’s Christmas” (1906), and it has been suggested that she served as a model for Aunt Tillie in The Song of the Lark (1915). Cather frequently mentions in letters to other family members that she received long letters from Seymour full of family news, and she urged her sister Elsie Cather to care for Seymour during her final illness and sent money to pay medical expenses.

Yeiser, James (1878-1953) (“Jim”). Reporter; Cather's childhood friend. James Dillard Yeiser, born in Red Cloud, NE, was the youngest child of Baptist minister and Webster County judge George O. and Almira Dillard Yeiser. About the age of Cather’s brothers Roscoe and Douglass, he was one of the playmates of the Cather family, and part of the play-town of Sandy Point that they created. Jim Yeiser graduated from the Red Cloud high school in 1897, studied law at the University of Nebraska in Lincoln 1897-99, and then went to California, working as a reporter for the San Francisco Examiner until his retirement. Cather kept in occasional touch with him; he once wrote her that he would be happy to do a favor for the mayor of Sandy Point.
