Joan was born in Florence. She lived during the first century of the Order.
When she received the habit of the Third Order of the Servants, she pledged herself to the Virgin Mary. She lived a life of chastity and penance.
Several ancient images represent Joan as one of the more distinguished blessed of the Order. Pope Leo XII confirmed the devotion to her in 1828.
O God, by your grace and the austerity of her life, Joan remained faithful to her consecrated love for Jesus. Grant that we by her prayer and example, may experience conversion of heart so that we may love and serve you above all things. We ask this through our Lord Jesus Christ.
