I posted a related question here so it might be helpful to read it:
B: unknown England
Marriage: 1766 Stillingfleet to Jane Hare, Yorkshire and he was living in Thorganby at the time
Research Question: When and where was Thomas Fowler born?
As we are in the 1700s now there are no census records or civil registration records. All that exists are church records for birth, marriage, and burial. Some people might have had a will and there was a probate court in York. That's all there is. Only one institution has the church records because it's a small village and there was only one church there.
The keeping of parish records date back to 1538 when Cromwell, at the Court of Henry VIII, ordered that every wedding, baptism and burial should be recorded.
Available sources: church records held at the Borthwick Institute for Archives
I asked the archivist and he said that there are no known gaps in the records and no known missing or destroyed records. "We hold the original records for the parish at the Borthwick Institute. Registers 1-9 (covering christenings, marriages and burials during the period 1653-1885) are available to view in the first instance via microfilm at the Institute."
This is from the archivist: https://borthcat.york.ac.uk/downloads/pr-thorg.pdf
It reads like the records cover baptisms from 1653 - 1885.
The FindMyPast website has the images for the records. https://www.familysearch.org/wiki/en/Thorganby,_Yorkshire_Genealogy https://archiveshub.jisc.ac.uk/search/archives/0d99c682-fc95-30d2-a39c-cddc8490317c
I also found a detailed history of Thorganby but it doesn't mention any 'Fowlers': https://www.british-history.ac.uk/vch/yorks/east/vol3/pp112-120
Also, the British Newspaper archive could be a source but why list it if there are no record matches?
What are some reasons why this would not meet the GPS if there is only one source afterall?
