George Washington became stepfather to John Parke "Jacky" Custis, then four, when he married the boy's mother in January 1759. Knowing that the youth would inherit great wealth from the Custis family, Washington earnestly sought to give his stepson a proper education and a full understanding of prudent financial management. Jacky consistently frustrated Washington through his inattentiveness to formal studies and decided preferences for amusements like hunting, horse riding, and socializing. He particularly upset his stepfather when he married at a young age and abandoned his formal education. Jacky's marriage brought joy to his mother and stepfather in the form of grandchildren, but his mismanagement of land transactions and business affairs aggravated Washington beyond measure. Jacky's death from a fever on November 6, 1781, after briefly serving as a volunteer aide to Washington at Yorktown, cut short his life and caused anguish for his mother and wife but likely spared much additional distress for his stepfather who lamented his failure to instill sounder habits in his stepson.

Benedict Arnold's name immediately conjures traitorous thoughts. This was not always the case. During the American Revolution, George Washington initially saw Arnold as a brave and highly capable officer, and he advocated Arnold's promotion to major general and placement in significant commands. A man of prickly temperament, Arnold viewed these advances as coming too slowly and with too little respect and rewards. He turned his attention to the British, commenced a clandestine correspondence, and hatched a plot to hand over the strategic post at West Point. The fortuitous capture of Major John Andre, Arnold's British contact, led to the plot's discovery before its fateful execution and Arnold's flight from his former Continental compatriots. The treason instantly converted Arnold to Washington's most hated enemy and began persistent but ultimately futile efforts to secure and hang the traitor.

Alexander Hamilton's intellect and ambition propelled him from the obscure beginnings of an illegitimate birth on an island in the West Indies to a place among George Washington's trusted associates. Recognized for his competence as an artillery officer, fluency in French, and way with words, Hamilton came into Washington's military family as an aide-de-camp in 1777. Hamilton excelled in that role until frustration with its limitations and a spat with Washington led to the young officer's departure in early 1781. Hamilton achieved his yearning for military glory after receiving a command in the light infantry and leading a successful assault on a key redoubt prior to the British surrender at Yorktown. With the war winding down, Hamilton turned his sights to politics and raising a family with his wife, Elizabeth, the daughter of Philip Schuyler, a prominent New Yorker as well as one of Washington's confidants. Hamilton's close relationship with Washington, along with their shared ideas regarding the need for a strong central government, promised significant future contributions to the growth of the United States.
