In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Cefn like this:
CEFN, a hamlet in Gelligaer parish, Glamorgan; 6½ miles N of Caerphilly. Real property, £9,719; of which £7,191 are in mines. Pop., 659. Houses, 120.
The location is where the name "Cefn Hengoed" appears on the modern 1:25,000 map. "Cefn Gelligaer" is the name of an area of common north of Gelligaer, but is too far north to fit the distance from Caerphilly given by the descriptive gazetteers.
A Vision of Britain through Time includes a large library of local statistics for administrative units. For the best overall sense of how the area containing Cefn has changed, please see our redistricted information for the modern district of Caerphilly. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Cefn and units named after it.
