The local churches do have registers of baptisms, weddings and deaths. These can be helpful in tracing relatives etc. Although all information is subject to the Data Protection Act, some information connected with weddings and deaths is in the public domain and can be released. It is vital is to contact the parish, explain what you are hoping to find and make an appointment. If you arrive on speculation, you may find presbyteries busy places with priests unable & unwilling to drop everything in order to assist you! We are under no obligation to provide this help but if you prepare the way you are more likely to get a positive response.
