How much clearer could it be? Full name given, time span of 6 months, and location is a small town, though admittedly there will be non-conformist places of worship as well as the parish church.
FreeREG coverage for Chapel-en-le-Frith doesn't go beyond 1837, and PR images at Ancestry stop at 1918, so no help there.
The best hope is someone local who knows how to access more recent registers or films etc that haven't gone online yet.
