Kingdom of Desmond
The MacCarthys of Muskerry, on the other hand, derived more recently from the MacCarthys Mór, and so were (and still are) considered a sept of the main dynasty. This principality of the Kingdom of Desmond began in the 14th century as an appanage of King Cormac Mór MacCarthy Mór (d. 1359) for his second son, Dermod. At various times, because of their adeptness at playing the political game with England, the Lords/Princes of Muskerry also bore various British titles, such as Earl of Clancarty, Viscount Mountcashel, and Baron (Lord) of Blarney.
