About us

Inspired by events put on that year by Cookstown council, the Stewartstown march and the soon to be opened Hill of O’Neill in Dugannon, a few O’Neill’s together in 2012 and decided the time was right to resurrect a fully functioning O’Neill clan, it went under the name O’Neills of Ulster / Ancient clan O’Neill of Tyrone. The small group in Ulster were quickly joined by O’Neill’s from North America, Australia, Canada and Britain. 

In three years we evolved from a think tank to a fully functioning Clan with a strong hard working committee in Ulster and four branches in the USA. We have come of age in 2015, updated our constituent, changed our name to The Ancient Clan O’Neill, so that all O’Neills from around the world feel free to join us, we created a new crest to represent every O’Neill, Neel, Neil, Neal, Niel and the many variations of the of the name and hope you look on it with pride.

Hammering Harrington: the battle of Deputy's Pass, 29 May 1599

Apologies for being away for a while there. Back in August last year, I had a whole rush on blogs; then I leave you all hanging until now.

When you absolutely positively gotta kill almost half of Mountjoy's army … the Moyry Pass, 1600, accept no substitute.

OK, I’m past the point justifying my unhealthy attention paid to Hugh O’Neill’s battles against the English crown, that’s just how this scrivener rolls.

Gaelic primitivism? Give it a rest. The Nine Years War (1593-1603) and the zenith of native Irish military power.
