Manuel Rodriguez from Mazamitla, Jalisco

Hello,

I have been researching my father's family for a while, and it all has been a straightforward process--until now. I am trying to find the marriage records for my great great grandfather Manuel Rodriguez and my great great grandmother Trinidad Silva, who were presumably married in Mazamitla, Jalisco in 1865. Manuel Rodriguez is the son of Jose Jesus Rodriguez and Maria de Jesus Martinez. Trinidad Silva is the daughter of Vicente Silva and Rita Silva. I have parsed through the marriage records for Mazamitla and nearby Quitupan, but marriage records do not exist for 1864-1867 and 1862-1867, respectively. Their marriage records are the only thing that could tell me where they came from, seeing as nobody in my extended family knows. Do I look in military records? Do I leave open the possibility that they may have come from elsewhere? What other resources do I turn to? Thanks in advance.
