I use this a basic convention for files, FirstLasttype.
For John Doe the file name \
Birth: John Doe Birth certificate" or "John Doe Birth Record"
Census: "John Doe 1850 census".
Death: John Doe Death certificate" or "John Doe Death Record"
When you get the situation like my family the like to name after ancestors and have four generations of John Doe I add the birth date.
John Doe 1854 1850 Census, John Doe 1830 1850 Census, etc.
I have found no standard is a perfect match for all occasions so there are some variations. like "John Doe B 1854 Census 1850"
