Note: OPR stands for Old Parochial Registers, which are the earliest records of baptisms, marriages, and burials kept by The Church of Scotland. The OPR number is useful, and often necessary, in tracking down these records. The Church of Scotland kept the records before civil registration was introduced in 1855. Civil registration district numbers (RD numbers) are included in the timelines on the Parish pages. See the All Parishes Index for ancient parishes and parishes created or subdivided from older parishes.
