St. Juan Diego
St. Juan Diego was born in Cuauhtitlan (in modern-day Mexico) in 1474. This poor farm worker converted to Christianity when he was about 50 years old. The Virgin Mary appeared to him at Guadalupe in December 1531. This image of her became known as Our Lady of Guadalupe. He died in 1548. Juan Diego was canonized in 2002 by Pope John Paul II.
