Like Melanie mentioned, you will need to know the name of the cemetery category.
- From edit mode on the profile, click the category picker icon
and start typing the name of the cemetery. If the cemetery already exists, then you can select it form the list and it will be added to the profile.
- If the cemetery category does not yet exist, then it will need to be created. There is a guide available here.
If you are not comfortable trying to create the category yourself, or would like some assistance during the process, you can use the 'request a new category or advice' link from the edit mode of a profile (look in the right-hand column under the How to Add Categories header) and provide as much information about the cemetery as possible (name, location, etc.).
