High on the limestone plateau of the Burren, on a cliff edge overlooking the valleys of north Clare, stands Cahercommane — the triple-ring stone fort that served as the ceremonial capital and inauguration site of the Chiefdom of Tulach Commáin. This is where the Chiefs of Ó Comáin were consecrated under Brehon law. It is one of the most spiritually charged sites in all of Munster.
The inner wall alone used an estimated 16,500 tons of stone. The fort was constructed in the 8th–9th century AD at the height of the Chiefdom's power, excavated by the Harvard Archaeological Expedition in 1934 under Hugh O'Neill Hencken, and extensively studied by the Discovery Programme in 2012. Its triple concentric rings — each a sacred boundary — mark it as a site of exceptional political and ceremonial importance. Here, before the derbhfine, the new Chief was consecrated in a ritual of Brehon legitimacy stretching back over a millennium.
Regarded by historians as one of the most important early medieval sites in Munster, Cahercommane is the spiritual heartland of Clan Ó Comáin. Its stones remember what the documents cannot fully record — the weight of ceremony, the voice of the assembled clan, the moment when a Chief became a Chief.
From the Augustinian ruins on the shores of Killone Lake to the Atlantic tower of Doonbeg, the clan's holdings span the breadth of County Clare — places of prayer, of power, of memory and of lineage. Each site carries its own chapter of the clan's history, inscribed in stone and water and sacred ground.
Newhall House is the seat of Clan Ó Comáin and the residence of the Commane's Fergus and Maria Kinfauns. A handsome house set in mature demesne lands in the parish of Killone, County Clare, it stands on the site of the former Killone Castle — Newhall House is said to have been built with stones from Killone Castle, and the basement of the house is believed to incorporate part of the original castle structure.
The estate encompasses Killone Abbey, the Holy Well of St John the Baptist, Killone Lake and extensive agricultural and woodland grounds. The estate is the administrative and spiritual centre of the clan's revival. The gate lodges and estate walls date to the same Georgian period as the house.
Clan gatherings, revival festivals and formal clan occasions are held on the estate, which is in active private use. Access to Killone Abbey is available with the owner's permission.
Killone Abbey — Mainistir Chill Eoin, the Church of John — was founded in 1190 by Donal Mór O'Brien, King of Thomond and Munster, for Augustinian canonesses. It was the first convent of Augustinian nuns in County Clare and one of only three cloistered nunneries remaining in Ireland. Its ruins stand on the northern shoreline of Killone Lake within the Newhall Estate.
The abbey became closely associated with the O'Brien dynasty — several abbesses were drawn from their ranks. Among them was Slaney O'Brien (d. 1260), daughter of the King of Thomond, described in the Annals of Inisfallen as "the most pious, most charitable, and most generous woman in all Munster." The abbey was suppressed in 1584 and recorded in ruins by 1617.
The Pilgrim's Path links Killone Abbey to Clare Abbey to the north. The site is protected under the National Monuments Acts, with guardianship vested in the Office of Public Works. It is privately owned by the Commane family — the custodians of its silence.
Heritage Ireland — Killone Abbey ↗
Adjacent to Killone Abbey on the northern shore of Killone Lake stands the Holy Well of St John the Baptist — a site of continuous veneration since at least the 6th century. The well is adorned with inscriptions, some dating to 1600, left by pilgrims across the centuries. Lord Walter Fitzgerald documented its inscriptions for the Royal Society of Antiquaries of Ireland in 1899.
The well is the sacred heart of the Newhall landscape. Each year on the Feast of St John the Baptist, an outdoor Mass is held at the well, continuing a tradition of pilgrimage that predates the Norman arrival in Ireland. It is deeply bound to the spiritual life of the clan's territory — the waters that sustained the nuns of Killone, the pilgrims of the Burren, and the people of the chiefdom before them.
The well, the abbey and the lake together form a sacred triangle within the estate — one of the most atmospherically complete early Christian landscapes in County Clare. The Commane family are its custodians.
On a hillock above the harbour village of Kinvara — Ceann Mara, "head of the sea" — stands the abandoned ruin of St Commán's Church, the ancient foundation of Saint Commán, patron of Clan Ó Comáin. The Dictionary of National Biography (1887) records that Saint Commán "also founded the church of Ceann Mara, now Kinvara" — placing this foundation directly at the southern edge of Galway Bay, within sight of the Burren and the ancestral landscape of the clan.
The church's antiquity is confirmed by the Annals of the Four Masters, which record the death of Ailbhe of Ceann Mhara in 814 AD — establishing that a church was already built and dedicated at this site by the early 9th century at the very latest. The 11th-century Voyage of the Uí Chorra describes the destruction of "the church of the holy old man Coman of Kinvara" at the hands of sea marauders — and records that the penitent brothers rebuilt it as an act of restitution, a testament to the church's significance.
The site commands a remarkable position above Kinvara Bay, looking north across the waters of Galway Bay towards the Aran Islands. Dunguaire Castle, whose foundations date to the royal house of Guaire Aidne mac Colmáin, stands a few hundred yards away. St Commán's Church has been abandoned since the late 19th century and is severely neglected — a reminder of the urgent need for the clan's revival and stewardship of its sacred heritage.
Wikipedia — Coman of Kinvara ↗Doonbeg Castle — Dún Beag, the small fort — is a four-storey 16th century tower house on the Atlantic coast of west Clare, overlooking the Doonbeg River and Doughmore Bay. In 1619, Daniel O'Brien, Earl of Thomond, conveyed Doonbeg Castle to James Comyn — a direct connection between the castle and the Ó Comáin / Comyn lineage documented in the historical record.
The castle's history reflects the turbulence of Gaelic Clare. Originally associated with the MacMahon lords of Corca Baiscinn, it was seized by Turlough MacMahon in 1585, reclaimed by the O'Briens in 1595 after a fierce siege, and granted to James Comyn in 1619. The Crown confiscated it in 1688 and it was sold in 1703. By the 19th century it had become a ruin, though local families continued to inhabit its floors into the 1930s.
The castle stands today as a ruin in the village of Doonbeg. Its connection to the Comyn name in 1619 is one of the clearest documentary links between the clan's lineage and a surviving Clare monument.
Ballymacooda — Baile Mhic Uada — is a townland in the Civil Parish of Kilmaley, in the Barony of Islands, County Clare: the same barony as Newhall House and Killone Abbey. The townland of 510 acres lies in the heart of the clan's ancestral territory, in the landscape between Ennis and the Burren that the chiefdom called home.
The townland is recorded in the Landed Estates database of the University of Galway — a resource documenting the landholding history of Irish estates from the 17th to the 20th century. Its Irish name, Baile Mhic Uada, preserves the Gaelic form of a family association with this land across the centuries.
Ballymacooda sits within the Barony of Islands — the same administrative unit that encompasses Newhall, Killone, and the townland of Tullycommon (Tulach Commáin), in the landscape the clan held for over a millennium. It is part of the broader constellation of clan territory that the Ó Comáin family occupied across medieval Clare.
Landed Estates database — Ballymacooda ↗The Rock of Cashel — Carraig Phádraig, St Patrick's Rock — was the ancient seat of the Éoganacht kings of Munster, one of the most powerful dynasties of early medieval Ireland. Rising dramatically from the Tipperary plain, it was the ceremonial and political capital of the Kings of Munster for over a millennium.
The Chiefdom of Tulach Commáin, and the Ó Comáin family's role as kings of the Déisi Munster, places them within the broader political world of Munster over which Cashel presided. The historian David Blair Gibson, in his landmark study of the chiefdom, and Claire Cotter (2012) in the Western Stone Forts Project, both note evidence suggesting a possible short-lived Éoganacht chiefdom centred at Cahercommane itself. The Uí Fidgeinti — the branch of Munster from which Cotter identifies the sub-king Commán who named the fort — were closely associated with the Éoganacht political world.
The connection between the Chiefdom of Tulach Commáin and the Kingdom of Cashel reflects the layered political geography of early medieval Munster — where local chiefdoms operated within, and owed allegiance to, the great royal dynasties whose seat was the Rock. Cashel is not a clan holding — it is the seat of the overlords under whose umbrella the clan's ancestors exercised their own power in north Clare.
Place names are among the most durable evidence of a family's historical presence — they survive conquest, plantation and anglicisation, embedded in the landscape long after documents have been lost. The Ó Comáin name is preserved not only in County Clare but across the ancient province of Munster, from Kerry to Cork.
In the Barony of Iveragh, County Kerry, a townland bears the Irish name Na Comáin — meaning simply "The Commanes." The survival of the family name as a place name in Kerry's ancient Iveragh peninsula is striking evidence of a related branch that retained territory there, geographically separated from the Clare line but sharing the same ancient origin.
The Kerry Commanes and the Clare Commanes in all probability descend from branches of the same ancient Munster family, separated by geography across more than a thousand years — the name preserved in the Kerry landscape just as Tulach Commáin and Cathair Commáin preserve it in Clare.
In Monanimy Lower, in the Barony of Fermoy, County Cork — the ancient heartland of Munster — a local place name records "Commane," embedding the family name in the Cork landscape. The Barony of Fermoy lies in the deep interior of Munster, far from the Atlantic coast but within the same broad province over which the Éoganacht kings of Cashel presided.
Together with the Kerry townland, this Cork place name suggests the Ó Comáin family's reach extended across the southwest of Ireland — the name woven into the landscape of Clare, Kerry and Cork alike, three counties, one ancient family.
The story of Ó Comáin did not end at the Irish shore. A Commane Road in Baldwinsville, New York — in Onondaga County, upstate New York — testifies to the family's Famine-era emigration to America in the 1840s and 1850s, when the name was carried west across the Atlantic along with hundreds of thousands of Clare families.
John Commane, recorded as a tenant in Ballyea townland, Killone parish in 1828, is absent from Griffith's Valuation of 1855 — indicating he either died in the Great Famine or emigrated in those years. In the American landscape, the family left a road name as their legacy — an echo of the ancient Clare chiefdom, embedded now in upstate New York.
Further still, the name appears in several locations in France — a legacy of the Wild Geese, the Irish Gaelic soldiers and nobles who fled into exile after the Jacobite defeat of 1691. These were the last defenders of the old Gaelic order, and among them were families of Ó Comáin descent who carried the name into the courts and regiments of continental Europe, where traces of it remain to this day.
A name that began in the stone forts of the Burren — that survived the Normans, the Plantation, the Penal Laws and the Famine — now lives on three continents. The diaspora of Ó Comáin is the diaspora of Gaelic Ireland itself.
A triple-ring fort on a cliff edge. A lakeside abbey where O'Brien abbesses prayed. A holy well whose waters have run for a thousand years. A tower on the Atlantic coast held by a Comyn in 1619. These are not merely properties — they are the physical memory of the clan, the landscape that shaped it, and the territory it is called to reclaim.
Clan Ó Comáin holds Newhall House and its demesne — the abbey, the well, the lake and the gate lodges — as a living inheritance. The revival of the clan is inseparable from the revival of these places as sites of pilgrimage, gathering and cultural memory for all who carry the name.
