I'd say not true Maureen. I am on the Kilmore Cemetery Trust and in 2007 did a volunteer project in the cemetery mapping, photographing and recording every headstone and grave. Most graves are back to back with another so some face one way and the other row the opposite. In Kilmore, for example, they either face east or west - that's just the way the plan was mapped out. However, we found that the Catholic part of the cemetery didn't always (rarely even) followed the plan. The rows are as crooked and go off at weird angles and sometimes the graves are all facing East, regardless of supposed rows or any other alignment! (I figure it's the Irish in them if you know what I mean!

)
Apparently, the Irish like to think that the sun will set on your back and rise on your face so a lot of the graves were pointed in that direction - I can only summise for that reason. Quaint I thought. Even found a couple of broken bottles upside down next to old graves.
What was interesting about Harrietville is that ALL the graves point the same way - in actual fact I think they looked to the north - (but that didn't rhyme!) It's pretty obvious that those that planted their relatives there wanted them to face the view. It also means that in places there are no paths between several rows of graves (I think up to seven from memory).
