XOCHIPILLI is originally spelled with one L only. XOCHIPILI
This is because the Nahuatl language is mostly spelled and read with Spanish phonetics. So, the name XOCHIPILI is prn. sho-SHEEP-ee-lee and not sho-sheep-ee-jee, which is what it would be prn. when spelled with a double L (ll), as in Spanish, Ll = English, J
