In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Bethesda like this:
BETHESDA, a hamlet in Llanllechid parish, Carnarvon; 4½ miles SE of Bangor. It has a post office‡ under Bangor; and has recently become populous in connexion with the neighbouring slate-quarries.
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 Bethesda has changed, please see our redistricted information for the modern district of Gwynedd. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Bethesda and units named after it.
