John Parke Custis was an American planter and politician, only son of Martha Washington before her marriage to George Washington. He is now known for his progeny, especially those raised by President Washington.

Martha Dandridge Custis Washington was the wife of George Washington, the first president of the United States. Although the title was not coined until after her death, she served as the inaugural first lady of the United States, defining the role of the president's wife and setting many precedents that future first ladies would observe. During her tenure, she was referred to as "Lady Washington". Washington is consistently ranked in the upper half of first ladies by historians.
