Hi Meleri, just to clarify something, Joseph's house is No 3 with the brown UPVC door and is on the left as you approach the village from the Betws y Coed direction. What's strange about Llewelyn Street is that there are a number of terraced cottages there and each terrace has a different name. I found out by asking at a house and when I got to Cwm Penmachno I was lucky enough to meet the postman on his round, but even he didn't know one or two places on the list I had
The main street has double yellow lines all along it but I parked my car opposite the Capel Salem. The family grave is straight ahead but slightly left as you walk through the gate but is quite distinctive by the metal chain that goes around the plot.
Good luck with your research on Joseph, it'll be interesting to hear anything that you find. My back is a lot better but walking is still limited and I'm certainly not fit enough to tackle those hills behind Cwm Penmachno. They are steep, very, very steep.
