Well, I would call those “lazy sources” ๐
If you found the information about the birth on the “Census 1834″ then Census 1834 is the source.
So too the Church book for county….”
It takes a little more effort to create a source, but it does make it easier in the long term. Once “Census 1834” or “Church book for county xxxx” exists as a source then a) it can be hidden easily, and b) it can be re-used easily for other birth records.
