"95 Roman. Pennant (Tours, 1778, pp.50-51; ed. 1810, i, 71; ed Rhys, i, 68) speaks of large quantities of lead scoriae and melted lead as having been found at the place called Pentre ffwrndan on the Ordnance sheet (9 N.E.; lat. 53° 14' 28", long. 3° 6' 55"), and he gives illustrations of Roman objects (fibulae, spoons, keys, amulets, etc.), which had also been found here. Sites of ancient furnaces are shown upon the Ordnance sheet, which are said to have been laid bare in 1840, and Mr. Henry Tayloy, F.S.A. (Historic Notices of Flint, p.8), adds that in comparatively recent times, "coins, pieces of glass, tiles, and other evidences of Roman occupation have been found at Croes Ati," which is cose to the Pentre. This place is colloquially called, 'Pentre ffwtan' or 'ffwdan'; the form 'Pentre ffwrndan' is first found in Pennant." (RCAHMC Wales & Monmouth)
