I am sorry but I do not have explanation to the Andrea's name according to the spanish naming conventions. Your ancestor was from Pontevedra (not Pontverda), Galicia, Spain, where there are several Acuña, even there is a thermal bath hotel (Balneario Acuña) to remember a spanish minister (uncle of my grandfather) who improve his health there..
Catean, Peniere, Penierre, Pincere has not meaning in spanish names or locations. I found some locations in Canada (Catean) or Italy (Pincere).
A frequent problem is the error of the civil records chairman, due to the date are provided not by the owner or simply there are writing errors.
Respect to genealogical records in Pontevedra it is impossible to have them because the Civil Registration start in Spain since 1870. Prior to that date you only can have information in the Catholic Church but you need to know the exact church or do the investigation in person. Cooperation is null usually.
You have a last opportunity with the Mormons (Church of the Saints of the Last Days). They have filmed thousands of church files across Spain. Contact with them. They are very gentle and perhaps they can help you.
