Never give up

I have been stuck for years on finding the parents of my 4th great grandfather Jose Ysidro Hurtado. I knew his name from baptism records and marriage dispensation of my 3rd great grandfather Rafael Hurtado but could never find Ysidro's parents names. I checked the baptism records of all of children I could find through LDS and no luck the parents were listed but not grandparents. Yesterday I was searching LDS and found the baptism record for Yisdro's youngest daughter Josefa Petronila De Jesus Hurtado and the grandparents were listed. This find was a double bit of luck in that I found Ysidro's parents were Francisco Hurtado and Augustina De Anda. The other bit of luck was that I was able to confirm with another source the parents of Ysidro's wife Rosa Munos.
Moral of the story genealogy isn't easy but eventually it comes together.
