Why was Our Lady of Guadalupe named Guadalupe?

When Our Lady first appeared to Juan Diego she told him her name was Our Lady of Guadalupe, or that is what was understood by Juan Diego. When he told the bishop of Mexico City, the bishop took it to mean Guadalupe in Spain, with which he was familiar. You must remember that Juan Diego spoke little Spanish and the bishop spoke little Nahuatl so words and sounds may have become misunderstood on both sides. However, the name has stuck now for nearly 500 years
