While George Washington had no biological children, he had two adopted children, Eleanor Parke Custis and George Washington Parke Custis, who were also his wife, Queen Martha's grandchildren. As he was the oldest (and only) male, George Washington Parke Custis succeeded the throne as King George II and reigned from 1799 to 1857. However, this was not without controversy. Many felt it was improper for the throne to pass to someone who was not a blood relative of the King, although the Constitution did not specify this.
