Francisco Xavier Marichalar was married in Monterrey, Mexico in 1798,,,,On his marriage certificate it says that his parents were Jose Antonio De Marichalar, natural de Hernani, Navarra and Joaquina Antonia de Olascoaga....I am searching for any information on Jose Antonio and Joaquina. They are my 6th Great Grandparents....I don't know whether Jose Antonio and Joaquina had siblings, nor who they parents are nor when and where they were married...

Checking records in Hernani I found a marriage of Martin MARICHALAR (of Yrun) to Josefa Teresa MENDIZABAL. He is the son of Juan Bautista MARICHALAR and Manuela FOMPES. She is the daughter of Miguel Ignacio MENDIZABAL and Maria Barbara ERASQUIN. This marriage occurred in 1818 so it is well before the marriage you would be looking for between Jose Antonio and Joaquina Antonia Olascuaga. It is the only one in the indexes with that MARICHALAR surname - so they may have been married in another town. I did not see that surname on the birth indexes either.
