Julian Alviso born 1865

I have been in search of my husband's grandparents birth and marriage records. I recently found them on a Valle de Guadalupe baptism of Jose 1/15/1906, son of Juan de Alva and Trinidad Jauregui. Trinidad was my husband's maternal great aunt. It listed Julian Alviso as 40 years old and from San Miguel and Catarina Jaurequi as 28 years old, but I could not read her place of origin. I was unable to print a copy yet as the printing machine in the history center has been out of service. Hopefully when I am able to print a copy, I will be able to read Catarina's place of origin with the help of a magnifying glass. Well on with my question. I now know that Julian was born approximately 1865 in San Miguel. The problem is I have gone through the microfilm batch J603298 and Source # 0279429 for San Miguel 1862-1870. I had ordered the film and went though the records by hand individually. There is no Julian Alviso. Julian has a total of six brothers and sisters and all of them were baptized at San Miguel El Alto. I have found his sibling's records, but no Julian. I know that Julian and Catarina exist as I have found five of their children and they are listed as sponsors on other baptisms. This is becoming very frustrating. My question is if possibly the microfilm is not a complete record? Also, was there another church in the vicinity of San Miguel El Alto that possibly Julian may have been baptized? Any suggestions on my next step?
