There are several references to Rev. Royal Warner, First Church of the Nazarene in the Long Beach Independent and Long Beach Press Telegram.

Montebello is just East of downtown Los Angeles and about 25 miles North of Long Beach.

I searched the L.A. Times, Long beach press telegram and the Long Beach Independent for an obituary using different search terms, so unless I missed something, I just could not find any thing more than the articles mentioned above.
