How did Washington assist the Marquis de Lafayette's family during his imprisonment by the French government as noted in the biography, Washington: A Life?

During Washington's terms as president, Lafayette became a source of uncertainty and indecision for Washington. Lafayette was arrested and held as an enemy of France's new government during the final years of the French Revolution. When Lafayette's wife begged Washington for help in getting her husband freed, he could not go against his own neutrality proclamation and could only provide her money for her personal use. Years later when Lafayette's son came to America, Washington was unsure of how it would look should he invite the boy to visit with him. In the end, however, Washington arranged to have young Lafayette stay at his home until his father's release from an Austrian jail after five years of imprisonment.
