 The first issue of the Royal Dublin Society Historical Studies in Irish Agriculture is a book on ancient Irish cattle breeds which states that white cattle were known in Ireland until at least the 1820s, although they became extinct in Ireland in that century.Similar references are found in Welsh history at a slightly later period.Pembroke in western Wales remained a main centre of the breed until the nineteenth century and they were driven in large numbers to the pastures of the Severn and the neighboring markets in England.
