In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Ynyscedwyn like this:
YNYSCEDWYN, a hamlet in the N of Glamorgan; at the confluence of the rivers Tame and Twrch, 13 miles NE by N of Swansea. Iron-works are here; and anthracite abounds in the vicinity, and was brought into use, in 1836, for the blasting of iron.
Ynyscedwyn is now part of POWYS District. Click here for graphs and data of how POWYS has changed over two centuries. For statistics about Ynyscedwyn itself, go to Statistics.
