I want to know the answer to the following question:
Who founded the Mission San Xavier del Bac?
All the background I'm provided with is that "Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agustín del Tucsón, on August 20, 1775 (near the present downtown Pima County Courthouse).". Is that enough to answer the question?
