I’ve added an article about Scottish Old Parish Registers (OPRs). It’s really helpful to fully understand the documents you use for research, and from reading genealogy forums I’m awqre that OPRs cause most of the frustrations. Our brickwalls most often happen because we just can’t find the baptism or marriage we need in the surviving OPRs, or we find an entry we think might be right but there just isn’t enough evidence to be certain.
In the article I’ve discussed the problems encountered by lack of detail in OPR entries, lack of an entry in the OPR even though a baptism or marriage probably did take place, lack of a baptism or marriage having happened in the first place, and difficulties reading and transcribing OPRs.
Hope you find it interesting and useful.
