In subsequent ages the family of O’Donoghoe split into three great branches; that of O’Donoghoe More, or the great, of which Ross Castle became the residence; O’Donoghoe of the Glens; and O’Donoghoe of Lough Lein. Of these three families the first and last are supposed to be extinct, and are at least reduced to poverty; but that of the Glens is still represented by O’Donoghoe of Killarney, who is consequently the reputed chief of this illustrious family. By a happy chance, very rare in Ireland, O’Donoghoe, who is as yet a minor, possesses a considerable portion of the estates of his ancestors of the Glens; but the properly of the O’Donoghoe More, or Ross, as well as that of the O’Donoghoe of Lough Lein, has been long in the possession of the noble house of Kenmare, of which their ancestor Sir Valentine Brown made a purchase from Donald M’Carty More, Earl of Clancarthy, as early as the year 1588, it having been forfeited by Rory O’Donoghoe More some time previously. These lands, as Dr Smith acquaints us, were subsequently confirmed to the grandson of the first purchaser, Valentine, son of Nicholas Brown, by letters patent of King James I. which passed the seal May 12, 1612, and included with others the entire country of Onaugh, alias Onaught O’Donoghoe More, in the county of Desmond, in which were contained the manor and lake of the Castle of Ross, with divers islands in Lough Lein, with all other his estate, containing 82 quarters of land, amounting to 6560 acres, besides the fishings belonging to the manor of Ross-I-Donoghoe, all which premises came to the family by immediate bargain and grant from the Earl of Clancarthy, by the indenture before mentioned. “But,” as Smith adds, “some question being made of the validity of this grant from the crown, the king, by privy seal, dated at Greenwich, 28th May 1618, directed Sir Oliver St John, lord-deputy, to accept a surrender thereof from him [Valentine], and to re-grant the same to him in fee by a new patent, for clearing all doubt, and the better settlement of his estate.”
