I meant to comment in a previous post on how a graveyard is a universal leveler. Even though this is mostly true - to some extent anyway - in the case of this cluster of graves it's clear that the family was segregated from the rest of the cemetery's residents. Not only this, but it even looks as though the people in the two graves in front were placed there to guard over those behind the fence. Spooky.
I should actually have read the inscriptions on the headstones - I have a feeling there's a particularly sad story about this cluster.
