Laud 610, Rawlinson B 502 & Book of Ballymote

The earliest extant Irish genealogical collections, Rawlinson B 502 (Rawl) in the Bodleian Library, Oxford, and the Book of Leinster (LL) in Trinity College, Dublin, date from the twelfth century; all the other genealogical sources survive from the late medieval or early modern period. The first of these, the Dublin Trinity College MS 1298 (H.2.7) (H) was written probably in the middle decades of the fourteenth century. Its contents are mostly of a genealogical nature, including a significant amount of material lacking in the two early manuscripts. It is followed by an almost contemporary manuscript, MS G 2 3 (G) preserved in the National Library of Ireland, Dublin. These two manuscripts are then followed in the last decade of the fourteenth century by two important collections, the Book of Ballymote (BB) and the Book of Lecan (Lec) both in the Royal Irish Academy, Dublin. They contain not only later medieval genealogies, but also versions of earlier material some of which is lacking in Rawlinson B 502, the Book of Leinster and MS 1298 (H.2.7). However, there is material in the MS Laud 610 in the Bodleian Library, Oxford, written mostly during 1453-54, which preserves material that dates from the eleventh century and primarily is related to the Northern Ui Neill.

Irish medieval manuscripts ususally employ two styles for recording genealogical information. The earliest sections are preserved in the ‘minigud senchais’ or ‘craeb coibnessa’, which outline the genealogical relationships between the kindred or descendants of a real historic ancestor or legendry figure believed to be a common ancestor. These tractates are usually found in the earlier sections of the manuscript, e.g. Sil Cuinn, and are recorded in two columns. The second style employs liner retrograde patrilines, which are usually set out in a series of columns with one or sometimes two names per line. These two styles are important to compare and below, I compare three manuscripts dating from different periods, Laud 610 (11th Century), Rawlinson B 502 (12th Century) and the Book of Ballymote (late 14th century).

Only the material relating to the Genealogical tracts of the Cenel Eogain are compared and were appropriate I will add notes on areas of interest in the future.

Note: Ancestrial lineage of the O’Donnellys originally O’Donnaghaile; Gaelic ‘Donn’ means ‘brown’ and ‘ghaile’ or ‘galach’ meaning ‘valient’.

The O’Donnellys of Druim Lighen, now anglicised to Drumleene in the parish of Clonleigh, north of Lifford in County Donegal. They were apparently expelled from Dumleene and later obtained land in the parish of Donaghmore, about two miles west of the town of Dungannon in County Tyrone, and renamed it Ballydonnelly. Shane O’Neill (Shane the Pround) was forstered by the O’Donnellys. The chief of the O'Donnelly clan was hereditary marshal of Hugh O'Neill's army and fought at the battle of Kinsale in 1603, when he and his men were slain. In 1614, Ballydonnelly was granted by King James I to Sir Toby Caulfield and renamed it Castle Caulfield.

AU 1177

Dun-da-lethglas was destroyed by John De Courcy and by the knights that came with him, and a castle was made by them there, wherefrom they twice inflicted defeat upon Ulidia and defeat upon Cenel-Eogain and upon Airgialla; where was killed Conchobur Ua Cairella[i]n (namely, chief of Clann-Diarmata) and Gilla Mac Liac Ua Donngaille, chief of Fir-Droma, and wherein was wounded with arrows Domnall Ua [F]laithbertaigh and he died of those wounds in the monastery [of Canons Regular] of Paul [and Peter] in Ard-Macha, after partaking of the Body of Christ and after his anointing and wherein were killed many other nobles. Now, Conchobur Ua Cairella[i]n before that (namely, in the Spring) inflicted defeat upon the Cenel-Eogain and upon Ua Maeldoraidh; where a great number of the Cenel-Eogain were killed, around the son of Mac Sherraigh and around many nobles besides.
