There is so much wonderful information that you can find within the DAR GRC Reports that can lead you to original records and/or be the only copy of that information in existence anymore. For example, a tombstone reading conducted in the 1920s-30s in a local cemetery may have recorded information that is no longer legible or in existence today.
Here is an example from the Cemetery, Church, and Town Records Collection (Volume 67 that I got from the NYS Library) of a tombstone reading for Hosmer Cemetery (now known as Oakland Rural) in the Town of Porter, Niagara County, NY:
One of the names listed above in the cemetery is Robinson Butler who died in 1858 aged 47 years. A search for the Butler surname was conducted on Find a Grave and Robinson was not listed amongst the search results.
Here is an example of transcribed baptisms from the Bible Records Collection (which sometimes includes Cemetery, Church, and Town Records) showing baptisms from St. Pauls Church in Lewiston, Niagara County, NY.
The above transcription was made in 1936. In doing a catalog search for church records in Lewiston, St. Paul’s church is not listed as an available record. It could be that the original record book no longer exists or, perhaps, that permission to view it today has not been given. Whatever the reason is, the GRC Report may be the only evidence of those baptism available to you at this time. It is secondary information that can, hopefully, lead you towards finding an original record.
