And for the health of his own soul, that of his wife, those of his father and mother, whose bodies rest here, he granted, for the better support of the canons, and to contribute to the relief of the poor, the churches of St. Senan, Enniscorthy, St. Brigid, near Ardles, and St. John, with all his land lying and situate near this house, the tithes of mills at Enniscorthy, timber from his woods, with liberty of feeding their cattle in the same, and all other necessary pasture.
