Question: Who did Honora Edgeworth decline the hand of, even as she had a romantic engagement with a British Army officer hanged as a spy by the Continental Army?

André; a Tragedy in Five Acts is a play by William Dunlap, first produced at the Park Theatre in New York City on March 30, 1798, by the Old American Company, published in that same year together with a collection of historic documents relating to the case of the title character, Major John André, the British officer who was hanged as a spy on October 2, 1780, for his role in the treason of Benedict Arnold.  The play does not go into the historic details, but rather presents a fictionalized account of the American debate over whether to spare or hang him.  Only three characters in the play are historic: André himself, George Washington (referred to throughout the text, except once in a passage inserted between the first two performances, simply as "The General"), and Honora Sneyd, who had been briefly engaged to André ten years earlier under the auspices of Anna Seward, who had done much to romanticize the affair in her Monody on Major André of 1781.  (Actually, Honora Sneyd had died of consumption some months before André's death, and never went to America.) <SEP> Francis Marion (c. 1732 – February 27, 1795) was a military officer who served in the American Revolutionary War.  Acting with the Continental Army and South Carolina militia commissions, he was a persistent adversary of the British in their occupation of South Carolina in 1780 and 1781, even after the Continental Army was driven out of the state in the Battle of Camden. <SEP> John André (2 May 1750 – 2 October 1780) was a British Army officer hanged as a spy by the Continental Army during the American Revolutionary War for assisting Benedict Arnold's attempted surrender of the fort at West Point, New York to the British. <SEP>  Sneyd was born in Bath in 1751, and following the death of her mother in 1756 was raised by Canon Thomas Seward and his wife Elizabeth in Lichfield, Staffordshire until she returned to her father's house in 1771.  There, she formed a close friendship with their daughter, Anna Seward.  Having had a romantic engagement to John André and having declined the hand of Thomas Day, she married Richard Edgeworth as his second wife in 1773, living on the family estate in Ireland till 1776.  There she helped raise his children from his first marriage, including Maria Edgeworth, and two children of her own.  Returning to England she fell ill with tuberculosis, which was incurable, dying at Weston in Staffordshire in 1780.  She is the subject of a number of Anna Seward's poems, and with her husband developed concepts of childhood education, resulting in a series of books, such as "Practical Education", based on her observations of the Edgeworth children.  She is known for her stand on women's rights through her vigorous rejection of the proposal by Day, in which she outlined her views on equality in marriage. Honora Edgeworth ("née" Sneyd; 1751 – 1 May 1780) was an eighteenth-century English writer, mainly known for her associations with literary figures of the day particularly Anna Seward and the Lunar Society, and for her work on children's education.
