Mmm, good question. I have it in front of me and its difficult to say. It certainly says 'Cath.' and after the dot, a letter/symbol that looks like 'll' but a bit more open at the top like a capital V, so it looks like ...... the Cath.V Parish Church .......... His hand writing is a bit curly and flourishing. Does it mean anything to anyone?
I should have said, John is from Scotland and his grandfather was a Church Minister in Inveresk, Midlothian. Until I do more research, I would expect that to be Church of Scotland, so I expect the Catholic angle doesn't really fit does it?
