He Nican Mopohua reveals that Juan Diego was Juan Bernardino’s nephew and, given the latter’s illness, he decided to take care of him rather than fulfill the Virgin’s order.
The Virgin then confirmed to Saint Juan Diego that his uncle had been miraculously cured. She herself appeared to Juan Bernardino, and it was him who told her name: Saint Mary of Guadalupe.
On the other hand, tradition states that Juan Diego was married to María Lucía, with whom he was baptized. He Vatican website indicates that the “Christian couple lived chastely until the death of their wife, who died in 1529.”
“Much has been said about whether he had children or not. Well, with María Lucía, his wife at the time of the apparitions, he did not have children,” says Villa Roiz.
