Who were Saint Juan Diego's parents?

Juan was a mat weaver but we do not know what his parents did.
We have virtualy no information about Juan Diego, much less about his parents. All that is known is that they were Aztecs who lived near Tenochitlan (modern-day Mexico City) in the 16th century. It took years of investigation before the Church would finally make a statement that Juan Diego really existed. Even today, some people debate that fact. Normally, to be declared a saint, the Church must examine the remains of the person before the process can get underway. However, they had to waive this requirement with Juan Diego as his grave has never really been located with any certainty.
