the one on the main road is the new church - all graves are in serried ranks - no grass (or at least very little).
Old Marown is on top of the hill opposite Ellerslie farm (turn left at crosby x-roads coming from Douglas) - look at photo on manxnotebook and you can see the grass and state it was in a few years ago - if you look at that photo the entrance from the road is along the diagonal thru the church - that part was always nicely mown but there is a section of the yard to the right of the photo vantage point that at the time was inaccesible as was another section in the left hand corner of the photo
