 Urban legend, however, states that "Tía Juana", which means "Aunt Jane" in Spanish, was a real person whose inn provided food and lodging to travelers.There is however no record of such an inn; in fact the first building in the area was built by Argüello in any case, after naming his ranch Rancho Tía Juana.In Southern California, Tijuana is often referred to as "TJ" or "T.J." Baja Californians have adopted this pronunciation as "Tiyei".
