Marriage and family

Robert E. Lee, around age 38, and his son William Henry Fitzhugh Lee, around age 8, c.1845

While Lee was stationed at Fort Monroe, he married Mary Anna Randolph Custis (1808–73), great-granddaughter of Martha Washington by her first husband Daniel Parke Custis, and step-great-granddaughter of George Washington, the first president of the United States. Mary was the only surviving child of George Washington Parke Custis, George Washington's stepgrandson, and Mary Lee Fitzhugh Custis, daughter of William Fitzhugh^[40] and Ann Bolling Randolph. Robert and Mary married on June 30, 1831, at Arlington House, her parents' house just across from Washington, D.C. The 3rd U.S. Artillery served as honor guard at the marriage. They eventually had seven children, three boys and four girls:

1. George Washington Custis Lee (Custis, "Boo"); 1832–1913; served as Major General in the Confederate Army and aide-de-camp to President Jefferson Davis; unmarried
2. Mary Custis Lee (Mary, "Daughter"); 1835–1918; unmarried
3. William Henry Fitzhugh Lee ("Rooney"); 1837–91; served as Major General in the Confederate Army (cavalry); married twice; surviving children by second marriage
4. Anne Carter Lee (Annie); June 18, 1839 – October 20, 1862; died of typhoid fever, unmarried
5. Eleanor Agnes Lee (Agnes); 1841 – October 15, 1873; died of tuberculosis, unmarried
6. Robert Edward Lee, Jr. (Rob); 1843–1914; served as Captain in the Confederate Army (Rockbridge Artillery); married twice; surviving children by second marriage
7. Mildred Childe Lee (Milly, "Precious Life"); 1846–1905; unmarried

All the children survived him except for Annie, who died in 1862. They are all buried with their parents in the crypt of the Lee Chapel at Washington and Lee University in Lexington, Virginia.

Lee was a great-great-great grandson of William Randolph and a great-great grandson of Richard Bland.^[41] He was also related to Helen Keller through Helen's mother, Kate, and was a distant relative of Admiral Willis Augustus Lee.

On May 1, 1864, General Lee was at the baptism of General A.P. Hill's daughter, Lucy Lee Hill, to serve as her godfather. This is referenced in the painting Tender is the Heart byMort Künstler.^[42]
