Taithleach of the Moy Ó Dubhda captured the country (especially Tireragh) from the English. Although he did capture it, I think that many of the same chieftains did not get hold of much of their native territories since then, for the family, grandsons, and great-grandsons of Sein-Bhrian divided the land among themselves, though they do not possess it today and only a very small portion of the aforesaid chieftains still survive.""
