An Album of Presidents and Their Children

George Washington
America's first President had no biological children, but he became stepfather to the two children of the widow Martha Custis when he married her in 1759: John "Jacky" Parke Custis, left in the c. 1761 illustration above, and Martha "Patsy" Parke Custis. Both of the Custis children met with untimely ends; Jacky joined his stepfather's army but died from dysentery soon thereafter, while Martha suffered from epilepsy and died at 17.
