1.) Be aware that FamilySearch.org is run by the Mormons, and they call the Catholic sacrament "christening" to distinguish it from full-immersion baptism which is baptising a living person into the Mormon Church, or which a living person performs in a Mormon temple on behalf of a deceased person. Since the Mormons are the ones qualified to speak for the Mormons, ("But we desire to hear of thee what thou thinkest: for as concerning this sect, we know that every where it is spoken against." Acts 28:22) I link to https://www.lds.org/topics/proxy-baptism?lang=eng which is written by the Mormon Church.
2.) The Catholic baptismal records found with marriage processetti are often transcriptions of the Latin baptismal registers and these give the date of baptism, but the birth can be confusing. Is there a book about how to translate the time of birth to determine the date of birth. It's like it says, born at third hour last night which could mean 3 o'clock in the morning. Did the Italian day start at midnight? And what does "hour twenty-four" mean? Is that yesterday or today?
