[[Category:Hopewell, Virginia, Cemeteries]] no space after colon? I'm not sure I understand what you are asking. I do know that I have made a lot of cemetery categories and every time I do, I have to have my handwritten notes out and another window open with an already categorized cemetery to follow as an example because it is hard for me to wrap my brain around the nesting and I still obsess over getting it right, so I totally understand why you are asking. For my handwritten notes I wrote out examples of one I created and how it needed to connect to the category tree:
[[Category:Liberty Cemetery, Liberty, Nebraska]] The Cemetery Name, the City(county if rural), the State.
-this needs to be connected to the lowest location level so [[Category:Liberty, Nebraska]]
-it also needs to connect to the County Cemetery level so [[Category:Gage County, Nebraska, Cemeteries]]. If the County Cemetery level does not exist yet (the dreaded red print) it would then need to be categorized with location [[Category:Gage County, Nebraska]] and State Cemetery level [[Category:Nebraska Cemeteries]]
In your example it has a City Cemetery level instead of County.
I hope this helps you, if not please ask more questions : )
