Eleanor Agnes Lee (February 27, 1841 – October 15, 1873) was an American diarist and poet. The fifth child of General Robert E. Lee and Mary Anna Custis Lee, she was a member of the prominent Lee family of Virginia and was affectionately called "Wiggy" and "Agnes" by her parents. In her youth, Lee kept a diary about her life at Arlington Plantation. In 1984, her diary was published posthumously under the title Growing Up in the 1850s, and was considered one of the first detailed accounts the private lives of the Lee family at Arlington. Lee also wrote poetry, often in letters to her family, inspired by real-life events including the American Civil War, the death of her favorite sister, Anne Carter Lee, and the execution of her beau and cousin, William Orton Williams.
