Donovan and O'Donovan are English forms of Ó Donnabháin, “descendant of Donndubhán,” the surname of a Munster family that began on the River Maigue in County Limerick, with its stronghold at Bruree, and moved about 1178 to southwest Cork, where its chiefs had their seat at Castle Donovan in Drimoleague parish. Blankets, mugs, pennants, an ornament and tees carrying both spellings are collected in our Donovan and O'Donovan Irish family gifts collection.
Quick answer: Donovan comes from Ó Donnabháin. The family took its name from Donnabhán son of Cathal, lord of Uí Fidhgheinte in tenth-century Limerick, who died in 980. Driven out of Limerick in the late twelfth century, the O'Donovans settled in Carbery in west Cork, where the leading branch, Clann Chathail (Clancahill), held land under the MacCarthy Reagh lords until the confiscations at the end of the seventeenth century. Cork is still the county of the name: in 1890, 175 of the 211 Donovan births in Ireland were registered there.
What Does the Donovan Surname Mean?
Rev. Patrick Woulfe’s Irish Names and Surnames lists O'Donovan and Donovan together under Ó Donnabháin, “descendant of Donndubhán.” He reads the personal name either as donn, brown, with dubhán, or as a compound of donn, brown, and dubh, black, with a diminutive ending. John Grenham’s surname history gives the same roots and translates the whole name as “descendant of the dark brown(-haired or complexioned) man.”
The man behind the name appears in the annals as Donnabhán son of Cathal. In the Four Masters’ spelling he is Donnabhan; Grenham writes Donnduban. Donovan and O'Donovan are the same surname with and without the Irish Ó, “descendant,” so a single family can appear under both forms from one record to the next.
Who Were the O'Donovans of Uí Chairbre and Bruree?
Woulfe says the O'Donovans were “originally chiefs of Ui Cairbre Aedhbha, a district lying along the banks of the River Maigue, in the present Co. Limerick,” with their stronghold at Bruree. The name of that place, Brú Rí, is glossed on logainm.ie as “(the) abode of kings”; it is now a civil parish in the baronies of Connello Upper and Coshma.
Their ancestor stood against the rising family of Brian Boru. The Annals of the Four Masters record under the year 974 that “Mathghamhain, son of Ceinneidigh, supreme King of all Munster, was treacherously taken prisoner by Donnabhan, son of Cathal, lord of Ui-Fidhgeinte,” who handed him over to Maelmhuaidh, lord of Desmond, to be killed. Under 976 the same annals record that Brian, son of Ceinneidigh, defeated the Norse of Limerick and Donnabhán together. Grenham gives Donnabhán’s death as 980.
Why Did the O'Donovans Leave Limerick for Cork?
Woulfe dates the break to about 1178, when the family “were driven from Ui Cairbre and forced to take refuge in South-west Cork where, with the aid of their old allies, the O'Mahonys, they effected a settlement in O'Driscoll's country of Corca Laoighdhe.” Grenham places the move in the late twelfth century and ties it to the struggle between the MacCarthys and the O'Briens for control of Munster. The neighbors who made room for them have their own stories in our O'Mahony surname history and O'Driscoll surname history.
What Was Clann Chathail and Where Is Castle Donovan?
In Cork the O'Donovans became a Carbery family. Their territory, Grenham writes, ran “from the south-east coast almost as far as the modern town of Bantry,” and their principal seat was Castledonovan, at the center of Drimoleague parish. The townland of Caisleán Uí Dhonnabháin, Castledonovan, is recorded on logainm.ie in the civil parish of Dromdaleague and the barony of Carbery West, with the spelling “Castledonevan” in 1601 and “Castle O'Donovan” in 1615.
The leading branch was Clann Chathail, anglicized Clancahill. The O'Donovan family history drawn from W. F. T. Butler’s work records that Clann Chathail paid rent to its overlord, MacCarthy Reagh, the MacCarthy lord of Carbery, and received the white wand of office from him. The O'Donovans were lords within that lordship rather than kings in their own right, and they shared west Carbery with the O'Driscolls, O'Mahonys and other Gaelic families.
What Happened to the O'Donovans in the Seventeenth Century?
Woulfe says the family kept “considerable power and extensive possessions down to the close of the Jacobite wars.” Grenham adds that the O'Donovans took an important part in the Catholic and Gaelic defense against the Cromwellian and Williamite campaigns, and that the chiefs were dispossessed in the confiscations at the end of that century. Colonel Daniel O'Donovan regained some of the property after the Treaty of Limerick and re-established the family seat at Bawnlahan, in the parishes of Myross and Castlehaven.
Is Every Donovan from the Same Family?
Not quite. Woulfe records a second name, Ó Donnamháin, also anglicized O'Donovan and Donovan: a family of Corca Laoighdhe that was already seated in O'Driscoll’s country before the O'Donovans of Uí Chairbre arrived. He cites John O'Donovan’s view that many of the Cork O'Donovans descend from that older family. Woulfe also notes branches of the Uí Chairbre family that settled in County Wexford and County Kilkenny; the Kilkenny line produced the scholar John O'Donovan.
Donovan is an Irish surname in every one of these lines. What separates them is the family, not the spelling, so parish and townland records matter more than the presence or absence of the O'.
Where Is the Donovan Name Found?
Robert Matheson’s survey of births registered in 1890 found 211 Donovan births in Ireland: 194 in Munster, 14 in Leinster, two in Ulster and one in Connacht, and 175 of the total in County Cork alone. His table of principal surnames ranked Donovan 67th in Ireland, with an estimated 9,900 bearers. The places in the family’s story after 1178, from Drimoleague to Myross and Castlehaven, all lie in west Cork.
How Can I Research Donovan Family History?
- IrishGenealogy.ie: civil births, marriages and deaths, and church registers for Cork and other dioceses.
- National Archives of Ireland 1901 and 1911 census: search Donovan and O'Donovan separately, then compare households in the same townland.
- Griffith’s Valuation: mid-nineteenth-century landholders, useful for placing a family in a Carbery parish.
- National Library of Ireland Catholic parish registers: baptisms and marriages, many before civil registration began.
- logainm.ie: townland names and early spellings for Drimoleague, Myross, Castlehaven and the Carbery baronies.
Search both spellings in every index. A family recorded as Donovan in the 1850s may be O'Donovan in 1911, and the change says nothing about a change of family.
