 The line of the later kings of Desmond, to Donal IX MacCarthy Mór (d. 1596) has long been extinct.It was into the pedigree of the Srugrena sept that the famous impostor Terence Francis McCarthy inserted himself.Playing a crucial role in exposing the impostor Terence McCarthy was the claim by Barry Trant McCarthy, a great nephew of Samuel Trant McCarthy, whose pedigree was accepted and registered in 1906 by the Ulster King of Arms, Sir Arthur Vicars, who also determined the McCarthys of Srugrena to be the senior surviving descendants of the medieval royal family.
