In this photograph by Jack E. Kightlinger, President Richard M. Nixon walks his eldest daughter, Tricia Nixon, down the aisle at her wedding on June 12, 1971. Tricia Nixon married Edward Cox at a ceremony in the Rose Garden on the White House Grounds, followed by a reception in the East Room. A gazebo was built for the ceremony, which was conducted by the Rev. Dr. Edward Latch. The greenery of the Rose Garden was dotted with roses of reds, pinks, whites, and yellows. The shade of green of the crabapple trees throughout was said to match the shade of the bridesmaids’ layered silk organdy dresses, made by Priscilla of Boston. Though there was an intimate number of invited guests, just beyond it, on the South Lawn, press tents captured the nuptials for the nation.

Tragically, on March 22, 1820, Stephen Decatur was mortally wounded during a duel. After his death, his widow Susan Decatur rented out the house to foreign ministers and several secretaries of state. The house was eventually sold and passed through several hands, including the Gadsby family, the U.S. Subsistence Bureau, and the Beale family. Marie Ogle Beale, a society maven, and the last owner, left the house to National Trust for Historic Preservation in 1961. In 2010, the White House Historical Association and National Trust entered into a co-stewardship arrangement of Decatur House.
