Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so St. David’s 0.0 sits below most of its state (29% of Arizona towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
NoteThe founding year comes from Wikipedia alone; no second source gives 1846.

What stands out about St. David’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
St. David was established as a result of the Mormon Battalion having earlier passed through the San Pedro River valley in 1846. One of the founders of St. David, Philemon C. Merrill, was a member of the battalion. The Mormon settlers of 1877 were part of a group that originally was to settle Lehi, Arizona. The town was named after David Patten Kimball. The early St. David settlers played an important role in establishing the subsequent surrounding settlements, such as Fort Huachuca and Tombstone, as they did much of the logging in the Huachuca Mountains to provide lumber for the construction of those locations.
As a tight-knit Mormon community, St. David managed better than other small towns in Cochise County during the Great Depression.
