Llugwy is the name of an old property near Pennal, a village on the A493 road in southern Gwynedd, Wales, on the north bank of the Afon Dyfi/River Dovey, near Machynlleth.
Their lineage is from Owain Gwynedd, the illustrious Prince of North Wales (12th cent.
On the opposite bank of the Dyfi from Llugwy lay Cei Ward, one of a number of riverside quays in the hamlet of Morben.
A document of 1792 records "Evan Anwyl of Llugwy in the parish of Pennal in the county of Merioneth, gent".
It is thought that the fort guarded a ford or ferry crossing of the river Dyfi on the Sarn Helen Roman road.
