"At age 15, the then Miss du Pont was orphaned along with her four siblings when her parents died just over a month apart. Her mother, Charlotte du Pont, had been committed to an insane asylum following an attack of hysteria likely brought on when she returned from a trip to Europe in search of a state of better mental health and relaxation, to find her children beaten, and nearly starved by their nurse. The emotional stress of the incident was too much to handle for the mentally fragile Charlotte. She was taken to an insane asylum where she died on August 19, 1877. Her husband would die twenty-nine days later on September 17th of consumption, aggravated by exposure from working in the family powder mills."
