Yes, not only is it American Independence Day, it's the memorial of Blessed Pier Giorgio Frassati. To learn more about him go here. He is in the The Loyola Kids' Book of Heroes by Amy Welborn under "Temperance."
(The Book of Heroes is organized in sections associated with the virtues. It was a challenge to place figures in various categories, since most exhibited all the virtues in vivid ways, of course.)
