Today I had a wander round Easington Lane cemetery as you requested. It's not a big place at all - perhaps 30 minutes to get round the lot.
However, I didn't see Patrick's grave.
Although there were several old gravestones, the vast majority are post WWII, so I wonder if there'd been an earlier cemetery in another location.
A few headstones had been tipped on to their face, so clearly I couldn't check these ones.
