"Barri Island is situated on the coast of Glamorganshire; and according to Cressy, took its name from St Baruc, the hermit, who resided, and was buried there. The Barrys in Ireland, as well as the family of Giraldus, who were lords of it, are said to have derived their names from this island. Leland , in speaking of this island, says ' The passage into Barrey isle at ful se is a flite shot over, as much as the Tamise is above the bridge. At low water, there is a broken causey to go over, or els over the shalow streamelet of Barrey-brook on the sands. The isle is about a mile in cumpace, and hath very good corne, grasse, and sum wood; the ferme of it worth a £10 a yere. There ys no dwelling in the isle, but there is in the middle of it a fair little chapel of St Barrok, where much pilgrimage was usid'. (The 'fair little chapel' has disappeared, and 'Barry Island' is now, since the construction of the great dock, connected with the mainland, it is covered with houses, and its estimated capital value is now £250, 000).
