Like many religious, fray Luis de Úbeda did not use his given name. The use of Úbeda probably referred to his place of birth in the Jaén province. Fellow expeditionary Juan Jaramillo gave his name as fray Luis de Escalona. There are instances where a priest gave the location where he took Holy Orders. Both towns have 16th century convents, so it remains unclear where fray Luis was from. Fray Luis remained behind in Tierra Nueva at Pecos Pueblo (New Mexico) and died there shortly after the Expedition headed back to New Spain.
