4. Pedigree Tables: Original Stock, Thomond Branch, O'Hurly Branch
Journal of the Cork Historical and Archæological Society, Vol. XI, 2nd Series, No. 67 (Jul–Sep 1905), p. 109
This page presents, side by side, the article's two parallel pedigree tables: the senior Thomond/O'Brien line running down through Brian Boru, and the O'Hurly branch descending from the same shared ancestor Blod through Urthuile, the family's actual namesake, down thirty generations in all to Donnell O'Hurly, living around 1660–70. The whole pedigree closes with a formal certification by Owen Connellan, Irish Historiographer, dated 1836.

"The foregoing statements of facts, as far as I have power to test them by strict examination and research, appear to me to be correct in every particular, and in proof of my opinion I affix my signature hereunto." — Owen Connellan, Irish Historiographer to His Majesty. Dated 7th March, 1836, Royal Irish Academy.
The two columns above were printed in a specialized Gaelic typeface (Cló Gaelach) in the original, which does not survive OCR or casual transcription reliably — hence the original need for the reconstructions above, now superseded by direct verification against a clean scan. No cells in either column remain flagged as uncertain as of this pass. Unlike the O'Hurly column, the printed Thomond column gave an English gloss for only a few entries — mostly dates and notes, reproduced above; where none was printed, the cell is left as a dash, as in the original.
Historical Note — What Was a Clan?
Before reading these tables, it helps to know what a document like this is actually claiming. A Gaelic "clan" or sept was not simply an extended family in the modern sense — it was a political and territorial unit, typically all claiming descent from one named ancestor (hence "Ó [name]," meaning "grandson/descendant of," or "Mac [name]," "son of"), holding a defined tribal territory (a tuath), and led by a chief chosen from within a small circle of eligible senior kinsmen rather than by strict eldest-son inheritance. Each significant clan of any standing retained its own hereditary specialists: a bardic poet-historian to record and recite its genealogy and deeds, and often a Brehon family (see the glossary in Section 3) to administer law. Genealogy was not incidental to this system — it was the legal and political basis of land claims, chiefly succession, and status, which is exactly why families like the O'Hurlys paid scholars such as Owen Connellan to formally "make out and authenticate" a pedigree: a certified genealogy was itself a kind of title document. It's also why the deepest layers of these pedigrees, reaching back through kings of Munster to Milesius, function partly as history and partly as a claim to standing — a distinction Section 2's note on the "Milesian origin" discussed in more detail.
Historical Note — Urthuile, the Family's Namesake
Urthuile is the figure the O'Hurly surname itself comes from: Ó hUrthuile, "descendant of Urthuile." This isn't only the 1905 article's claim — it's independently confirmed by Patrick Woulfe's Irish Names and Surnames (1923), still a standard scholarly reference for Irish surname etymology, which describes the O'Hurlys as "a Dalcassian family in Thomond, akin to those of O'Moloney and O'Kearney," with "an important branch... settled at Knocklong, in the east of Co. Limerick, where the remains of their castle is still a conspicuous object on the Hill of Knocklong, and commands a magnificent view of the Galtee mountains and the plain of Co. Limerick." Beyond being a namesake, almost nothing else is independently recorded about Urthuile as an individual — which is typical for a figure this deep in a bardic pedigree, where the name may originally have functioned more as a genealogical marker for the sept's founding moment than as a remembered historical person.
A Note on Brenann Bán — a Pedigree with Two Shapes
Brenann Bán ("Brenann the Fair"), named here as one of Blod's four sons and the ancestor from whom the O'Hurlys descend, is also independently attested outside this 1905 article — but not in quite the same shape. John O'Hart's Irish Pedigrees (1892) gives the line as "Urthailé Árd, son of Heber (of the race of Brenan Ban), son of Blad, son of Cas," which treats Brenann Bán more as an ancestral "race" marker than as Blod's direct son with Urthuile several further generations down, the way this article presents it. Both versions agree on the same core cast — Cas, Blod, Brenann Bán, Urthuile — but disagree on exactly how the generations between them fit together. This is normal for pedigrees transmitted through multiple manuscript traditions rather than a single continuous record, and it's worth taking as a reminder that "the" O'Hurly pedigree, at this depth, was never a single fixed document even to the antiquarians who compiled it — it was reconciled, generation by generation, from several partially agreeing sources. (O'Hart's compilation is a useful cross-reference but has its own reputation among genealogists for occasionally presenting reconstructed lines more confidently than the underlying manuscripts support, so it should be read as corroborating rather than as a tie-breaking authority.)
Historical Note — Brian Boru
Brian Bóroimhe (Brian Boru), appearing here in the Thomond column as the shared ancestor's most famous descendant, is the best-documented figure on either table: High King of Ireland from 1002, and the Dalcassian chief whose reign broke the political dominance of the Uí Néill dynasties that had held the high kingship for centuries. He was killed, already elderly, at the Battle of Clontarf in 1014, in a battle usually remembered as ending large-scale Viking political power in Ireland, though Brian's own forces suffered heavy losses too. His father Céinnéidigh (Kennedy), listed just above him here, gives his name to the modern surname Kennedy. Brian's descendants took the surname Uí Bhriain (O'Brien) directly from him, becoming the Earls of Thomond — the "senior" branch this table sets the O'Hurlys' descent against.
Glossary
Tuath
A petty kingdom or tribal territory, the basic political unit of early medieval Ireland; Ireland at various points is estimated to have contained well over a hundred of them, each with its own king or chief, layered under larger overkingships such as Munster or Thomond.
Cló Gaelach
The distinctive Gaelic typeface, based on medieval Irish manuscript letterforms, used for printing Irish-language text from the 16th century onward and still common in Irish-language printing well into the 20th century. Its letterforms differ enough from standard Roman type that unfamiliarity with it, rather than any flaw in the printing, is usually what defeats casual transcription or OCR.
