We have been informed that the Office of Chief Herald has reconfirmed in writing that it has no intention of trying to reinstitute a new policy of ‘courtesy recognitions’ of chiefs-of-name.
And that the whole subject of title successions is not part of its brief;

7 December 2011: no reply has yet been received to inquiries made.

19 December 2011: a reply has been received, from Dr. Jean MacCarthy, and answered.
The Kanturk MacCarthy Clan organisation is not at all active at this time.
And, as reported earlier, the organisation that existed in the United States has been dormant for years. And attempts to contact previous officers of that group have been unsuccessful.

December 2011: The Association is pleased to note the creation of The MacCarthy Clan Foundation, an organisation that hopes to facilitate the (re-) establishment of MacCarthy Clan groups worldwide.
It will provide a centre for communication and liaison for all MacCarthy clan groups which develop over time, in whatever country, while allowing the Chief-of-Name, The MacCarthy Mór, a forum to express his views on various subjects.
See below for link to the site.
The Foundation is of course under the direct authority of The MacCarthy Mor, and will be administered as he delegates to his chancery or family members.
We should also say that on the new Clan Foundation site McCarthys will find a link to the McCarthy DNA project – which appears to be very active and well-managed.
