Some context: Robert Stewart, 2nd Marquess of Londonderry,  (18 June 1769 - 12 August 1822), usually known as Lord Castlereagh, which is derived from his courtesy title Viscount Castlereagh, (UK:  KAH-s@l-rey), was an Irish/British statesman. As British Foreign Secretary, from 1812 he was central to the management of the coalition that defeated Napoleon and was the principal British diplomat at the Congress of Vienna. Castlereagh was also leader of the British House of Commons in the Liverpool government from 1812 until his suicide in August 1822. Early in his career, as Chief Secretary for Ireland, he was involved in putting down the Irish Rebellion of 1798 and was instrumental in securing the passage of the Irish Act of Union of 1800.
Robert Stewart was born in Henry Street, Dublin, Ireland, in 1769 the son of Robert Stewart (1739-1821) of Newtownards and Comber in County Down, with properties in Counties Donegal and Londonderry. The family seat was Mount Stewart, County Down.  The elder Stewart was an Irish politician and prominent Ulster landowner He was created Baron Londonderry in 1789, Viscount Castlereagh in 1795, and Earl of Londonderry in 1796 by King George III. In 1771 he was elected in the Whig interest to the Irish House of Commons, where he was a supporter of Lord Charlemont and his allies who called for greater independence from Britain. From the Act of Union of 1800, however, he sat in the British House of Lords as an Irish representative peer. In 1816 he was created Marquess of Londonderry by the Prince Regent.  Stewart's mother, who died in childbirth when he was a year old, was Lady Sarah Frances Seymour-Conway, daughter of Francis Seymour-Conway, 1st Marquess of Hertford (a former British Ambassador to France (1764-65) and Lord Lieutenant of Ireland (1765-66)) and Isabella Fitzroy, daughter of Charles FitzRoy, 2nd Duke of Grafton. His father remarried five years later to Lady Frances Pratt, daughter of Charles Pratt, 1st Earl Camden (1714-94), a leading English jurist and prominent political supporter of both the 1st Earl of Chatham and his son, William Pitt the Younger. Through the elder Stewart's marriages, he linked his family with the upper ranks of English nobility and political elites. The Camden connection was to be especially important for the political careers of both him and his elder son. By Frances Pratt, Stewart's father had ten children who survived to adulthood, including Stewart's half-brother, Charles William Stewart (later Vane), Baron Stewart of Stewart's Court and Ballylawn in County Donegal (1814) and 3rd Marquess of Londonderry (1822).  In 1794, Stewart married Amelia (Emily) Hobart a daughter of John Hobart, 2nd Earl of Buckinghamshire, a former British Ambassador to Russia (1762-65) and Lord Lieutenant of Ireland (1776-80). Her mother, Caroline Conolly, was the granddaughter of William Conolly, Speaker of the Irish House of Commons in the early 18th century and one of the wealthiest landowners in Ireland. Caroline's brother, Thomas Conolly, was married to Louisa Lennox, sister of Emily FitzGerald, Duchess of Leinster, whose son and Emily's cousin-by-marriage, the aristocratic rebel Lord Edward FitzGerald, was a leader of the United Irishmen and one of their martyrs in the early stages of the Irish Rebellion of 1798.  Emily Stewart was well known as a hostess for her husband in both Ireland and London and during some of his most important diplomatic missions. In later years she was a leader of Regency London high society as one of the Lady Patronesses of Almack's. She is noted in contemporary accounts for her attractiveness, volubility and eccentricities. By all accounts, the two remained devoted to each other to the end, but they had no children. The couple did, however, care for the young Frederick Stewart, while his father, Stewart's half-brother, Charles, was serving in the army.

Some context: Susan Keating Glaspell (July 1, 1876 - July 28, 1948) was an American playwright, novelist, journalist and actress. With her husband George Cram Cook she founded the Provincetown Players, the first modern American theatre company. During the Great Depression, she served in the Works Progress Administration as Midwest Bureau Director of the Federal Theater Project. Glaspell is known to have composed nine novels, fifteen plays, over fifty short stories, and one biography.
Susan Glaspell was born in Iowa in 1876 to Elmer Glaspell, a hay farmer, and his wife Alice Keating, a public school teacher. She had an older brother, Raymond, and a younger brother, Frank. She was raised on a rural homestead just below the bluffs of the Mississippi River along the western edge of Davenport, Iowa, on property bought from the US Government by her great-grandfather following the Black Hawk Purchase. Having a fairly conservative upbringing, "Susie" was remembered as "a precocious child" who would often rescue stray animals. With the family farm increasingly surrounded by residential development, Glaspell's worldview was shaped by the pioneer tales of her grandmother, who told of regular visits by Indians to the farm in the years before Iowa statehood. Growing up directly across the river from Black Hawk's ancestral village, Glaspell was also influenced by the Sauk leader's autobiography; he wrote that Americans should be worthy inheritors of the land. During the Panic of 1893, her father sold the farm and Glaspell moved with her family into the city.  Glaspell was an accomplished student in Davenport's public schools, taking an advanced course of study and giving a commencement speech at her 1894 graduation. By age eighteen she was earning a regular salary as a journalist for a local newspaper, and by twenty, she wrote a weekly 'Society' column which lampooned Davenport's upper class. At twenty-one Glaspell enrolled at Drake University, against the local belief that college made women unfit for marriage. A philosophy major, she excelled in male-dominated debate competitions, winning the right to represent Drake at the state debate tournament her senior year. A Des Moines Daily News article on her graduation ceremony cited Glaspell as "a leader in the social and intellectual life of the university." The day after graduation, Glaspell began working full-time for the Des Moines paper as a reporter, a rare position for a woman, particularly as she was assigned to cover the state legislature and murder cases.  After covering the conviction of a woman accused of murdering her abusive husband, Glaspell abruptly resigned at age twenty-four and moved back to Davenport to focus on writing fiction. Unlike many new writers, she readily had her stories accepted and was published by the most widely read periodicals, including Harper's, Munsey's, Ladies' Home Journal, and Woman's Home Companion. It was a golden age of short stories. She used a large cash prize from a short story magazine to finance her move to Chicago, where she wrote her first novel, The Glory of the Conquered, published in 1909. A best-seller, The New York Times declared, "Unless Susan Glaspell is an assumed name covering that of some already well-known author--and the book has qualities so out of the ordinary in American fiction and so individual that this does not seem likely--The Glory of the Conquered brings forward a new author of fine and notable gifts." Glaspell's second novel, The Visioning, was published in 1911. The New York Times said of the book, "it does prove Miss Glaspell's staying power, her possession of abilities that put her high among the ranks of American storytellers." Her third novel, Fidelity, was published in 1915. The New York Times described it as "a big and real contribution to American novels."
Was her novel well received by the public or critics?
