Lee, whose mother was a cousin of Mrs. Custis, frequently visited Arlington. Two years after graduating from West Point, Lieutenant Lee married Mary Custis at Arlington on June 30, 1831. For 30 years, Arlington House was home to the Lees. They spent much of their married life traveling between U.S. Army duty stations and Arlington, where six of their seven children were born. They shared this home with Mary's parents, the Custis family.
