Whether this castle was subsequently repaired or reconstructed by Red Hugh’s brother Rory, the Earl of Tirconnell, during the few years for which he held his earldom previous to his flight to Rome, does not appear from any document which has fallen under our notice, and we are inclined to believe that he did not do so. But be this as it may, the existing ruins retain no feature of a castle of the 15th century, but on the contrary are in every respect characteristic of the castellated residences of the reign of James I.; so that if it be of Rory O’Donnell’s age, he must have rebuilt the mansion from its foundation. It appears, however, at least equally probable that the present structure may owe its re-erection to Sir Basil Brooke, to whom a grant of the castle was made in 1610. But it is certain, at all events, that he repaired the castle and resided in it until his death in 1633; and two chimney-pieces which still remain are unquestionably of his time, as the arms on one of them testify. These arms, which are sculptured on two shields, are, on the first, those of Brooke impaling Leicester--the family name of Sir Basil’s lady; and on the second, those of Brooke only. These chimney-pieces, which are very splendid specimens of the architectural taste of the age, are faithfully represented in wood-cuts in the second volume of the _Dublin Penny Journal_, and are accompanied by an excellent notice from the pen, as we believe, of Sir William Betham. In this notice it is stated that the Castle of Donegal “was granted by patent, dated the 16th November 1610, to Captain Basil Brooke, for twenty-one years, if he should live so long, with one hundred acres of land, and the fishings, customs, and duties extending along the river from the castle to the sea. Captain Brooke was knighted 2d February 1616, by Sir Arthur Chichester, knight, Lord Deputy, and had a re-grant of twenty-one years, or his life, of the castle by patent, dated 27th July 1620, and on the 12th February 1623, he had a grant of the fee of the castle for ever.” According to the same authority, this “Sir Basil Brooke was a scion of the family of Brooke of Norton, in Cheshire, and his lady was Anne, daughter of Thomas Leicester of Toft, in that county. Henry Vaughan Brooke, Esq. Member of Parliament for the county of Donegal, was his descendant and heir-at-law, who left the estates of his family to his nephew Thomas Grove, Esq. who took the name and arms of Brooke by royal sign-manual in 1808. He died without issue, and the estates of the family went to Thomas Young, Esq. of Lough Esk, who also took the name of Brooke by royal sign-manual, dated 16th July 1830, and is the present possessor.”
