The long name was supposedly contrived in 1869 as an early publicity stunt to give the station the longest name of any railway station in Britain.[17] According to Sir John Morris-Jones the name was created by a local tailor, whose name he did not confide, letting the secret die with him.[18][19] This form of the name adds a reference to the whirlpool in the Menai Strait known as the Swellies and to the small chapel of St. Tysilio, located on a nearby island.[20] The final -gogogoch ("red cave") is supposed to have been an addition inspired by the Cardiganshire parish of Llandysiliogogo, rather than by any local features.[21]
