Ffestiniog was a parish in CantrefArdudwy; in 1284, Ardudwy became part of the county of Merionethshire, which became an administrative county in 1888.[5]Mary Evans (1735–89) founded a sect in Ffestiniog around 1780, whose believers held that she had married Christ in a ceremony held in Ffestiniog church. The sect soon died out after her death.[6]
The parish was created an urban district in 1894.[5] On 1 April 1974, under the Local Government Act 1972, Ffestiniog Urban District was abolished, becoming merged with other districts to form Meirionnydd District, which was itself abolished in 1996. Ffestiniog became a community with an elected town council.
Ffestiniog Golf Club was founded in 1893. The club closed at the end of March 2014.[7]
Toponymy
Celtic place-name in *-ākon "place of", then, "place belonging to, territory of" > Old Welsh -auc, -awg > Welsh -og. The form -iog with an additional /i/ can be explained by the preceding element, which is a personal name ending with -i-us : Festinius. The whole name should be *Festiniākon. Probably same name as Festigny (France, e.g.: Festigny, Marne, Festiniacus in 853). A Roman Inscription in Chester honours Lucius Festinius Probus;[8] Chester was the main Roman base for North Wales, so this is probably he.
