Frequently asked questions (FAQs)
Is the GPR a primary or secondary genealogic source?
The GPR is both a prinary and a secondary genealogic source.
The actual grave monument photographs are primary genealogic sources. This means that they are extremely good at providing the family history researcher with one of the three primary source facts that are recommended to prove a genealogical relaationship.
However, as with any primary source, there can be errors. Below are examples:
- Mason errors: incorrect information being written on the monument
- Spelling errors: where the information has been given by an illiterate relative.
- Date and age errors: where the information provided is guess work.
The GPR database must be considered as a secondard source. The information within it is based on the text read from the grave monument photograph. This process is subject to error especially when the monument is only just legible.
