 However, as historically insignificant as Ynysforgan may seem it holds a hidden gem unknown to most locals and has its name embedded in the annals of Welsh time.In the latter part of the Middle Ages (circa 1330 - 1403) Ynysforgan was the home of Hopcyn ap Tomas ab Einion.This clearly indicates the name Ynysforgan extends back further than the 15th century and given the 'modernisation' of language it's conceivable its name is derived from old Welsh.
