The burial registers for Nellfield Cemetery are searchable online at
www.deceasedonline.com. It's a pay per view site, but searches are free (much like Scotlands People). If it has a grave reference, you should be able to see the others who share that reference. Aberdeen City Archives (
www.aberdeencity.gov.uk/archives) have the actual burial registers.
There aren't any monumental inscriptions for Nellfield though, but if you find the location of the grave perhaps you could then ask someone to take a picture for you (if you can't go yourself!)
What is the date of the death / burial?
