Over a decade ago I posted to the Socorro County USGenWeb website a list of Delayed Birth Records for specific Socorro County residents born in the county between 1867 - 1885. Delayed Birth Records are types of official birth certificates issued to individuals when they were adults. This was done because a person would have requested to have a birth certificate for some official need, and would have been backed up by a baptismal record and affidavits.
Although I transcribed these records, I don't want to post the list on this site because they are copyrighted by USGenWeb. However, you can view the list at this link.
