Ash Wednesday: Saint of the Day, Margaret of Cortona

Saint Margaret of Cortona

I just had a discussion with a friend about Ash Wednesday, Judas, and St. Lucy.  But today, beyond being George Washington's birthday, is also Saint Margaret's day.  What Ash Wednesday is about.  Today is the start of Lent.  The Anchoress has some links of the subject.
