LYGAN-Y-LLAN (HELYGEN-LLAN), a hamlet, in the parish of HALKIN, Northop division of the hundred of COLESHILL, county of FLINT, NORTH WALES, 3 miles (S. E. by S.) from Holfywell: the population is included in the return for the parish. This hamlet, which contains the parochial church, derives its name from a saint called Lugan, of whom very little is known, but whose name occurs in the Welsh calendar. Lead-mines abound, in which many of the inhabitants are employed; and the late Sir George Wynne is stated to have cleared £300,000 from a single mine, discovered under a small tenement in the hamlet.
