Brian MacPhelim's son, Shane [Sean], changed the name of Edendubhcarrig to "Shane's Castle," after his own name, and was chosen by the English Government for "Captain of Clanaboy," on the grounds that "he was a modest man that speaketh English;" which shows that it was no particular right on Shane's part, but merely his friendly disposition towards the English, that was the cause of their preference in his favour. (See State Papers, Vol. CIV., 28, August 23rd, 1583). Shane's son Henry [only son by first marriage] conformed to the Protestant religion; was knighted, and got a patent from King James I., of the estates of "Shane's Castle;" and thus the old family domains of Edendubhcarrig passed to the posterity of the fourth son of Niall Mór, to the prejudice of the senior branch of the family who clung to the Catholic Faith. http://www.libraryireland.com/Pedigrees1/o-neill-3-heremon.php#note9

He had four sons by his second wife: 1. Arthur, of Shane's Castle, who was the heir of his brother Henry, in the event of his daughter Rose (Marchioness of Antrim) having no issue; 2. Phelim; 3. Shane Oge, who died without issue, A.D. 1620; and 4. Hugh, who also died, sine prob.
