Just caught this at the source link:
“Correction to This Article
An earlier version of this article in print and on the Web incorrectly identified the subject as Mary Lee Custis.”
The article is about Mary Custis Lee.
Known as "Daughter" or "Sister" to her family, Mary spent her most of her life traveling around the country and later the world. During the out break of the Civil War she was at home. She helped to pack up and leave Arlington house the beloved home of her mother and her childhood. Mary managed to get herself stuck behind enemy lines for close to a year, which grieved her father sorely. She was independent and outspoken for a woman of her time. Mary never married but did have many suitors. The most famous of which is JEB Stuart. Even though nothing came of the romance while at West Point they remained good friends until his death in May of 1864.
