Carrigkilter Research Hub
Carrigkilter is the principal land-evidence anchor for the documented Dargan / Dorgan family of East Cork. Parish records establish Patrick Dargan / Dorgan and Johanna / Anne / Nancy Flynn’s family from 1838, while valuation records place Patrick himself at Carrigkilter from 1847 onward.
This Research Hub brings together the 1847 Valuation Office Tenure Book, the 1848 House Book, Griffith’s Valuation of 1853, Ordnance Survey Sheet 89 and holding 8, parish evidence, maps, neighboring families, and later records.
Its purpose is to show how independent sources combine to establish the family’s connection with Carrigkilter while keeping unproved relationships, earlier ancestry, and later land succession clearly separate from confirmed evidence.
The family surname appears in East Cork records as both Dargan and Dorgan. For the historical background of these forms and the Irish surname Ó Deargáin, see Jerry Kelly and the Origins of the Dorgan Name.
Why Carrigkilter Matters
Carrigkilter matters because it is the strongest confirmed geographic anchor for Patrick Dargan / Dorgan and his family before later generations appear in Ballybraher, Cloyne, Churchtown South, and other parts of East Cork.
Parish records establish the family group from 1838, while land and valuation records place Patrick at Carrigkilter from 1847 onward. Together, these sources connect people, family relationships, and a specific holding within the local landscape.
Carrigkilter therefore serves as the starting point for reconstructing the documented family network. It is not treated as an ancestral location merely because other Dargan / Dorgan families lived nearby; each proposed relationship must be supported by documentary evidence.
Research Focus
The Carrigkilter research focuses on a small number of evidence-based questions: when Patrick Dargan / Dorgan first appears in the surviving land records; which holding can be securely associated with him; how the 1847, 1848, and 1853 records relate to one another; and what later valuation evidence may reveal about succession.
The research also examines neighboring occupiers, parish records, sponsors, witnesses, maps, and nearby Dargan / Dorgan households to determine whether any can be linked to Patrick’s family through documentary evidence.
A particularly important unresolved question is Patrick’s own parentage. The adult Daniel Dorgan who sponsored Mary Dorgan’s 1840 baptism is currently one of the strongest clues to an earlier generation, but his exact relationship to Patrick has not yet been proved.
The goal is to distinguish confirmed relationships from plausible but still unproven connections and to avoid promoting surname matches, proximity, or naming patterns into family relationships without supporting records.
Evidence Used in This Study
The Carrigkilter study combines several kinds of evidence, each answering a different part of the family story. Land and valuation records establish occupancy, property descriptions, landlords, map references, and changes in the holding over time.
Maps place numbered holdings such as map reference 8 within the surrounding East Cork landscape and help compare roads, boundaries, neighboring properties, and later revisions.
Parish and civil records identify baptisms, marriages, residences, sponsors, witnesses, and family relationships. Later census, directory, emigration, and naturalization records help follow the family after Carrigkilter.
Family tradition and local knowledge can preserve valuable clues, but they are kept separate from records that directly document a person, place, date, or relationship. Whenever possible, those clues are tested against original records before being incorporated into the family narrative.
Earlier Land History — 1667 William Penn Land Grant
Carrigkilter also appears in a much earlier seventeenth-century land-history context associated with William Penn. This material is useful for understanding the townland’s earlier estate history and the wider landscape in which later nineteenth-century holdings developed.
It is not evidence that the Dargan / Dorgan family occupied Carrigkilter in 1667, nor should it be used to imply continuity of ownership or residence from that period to Patrick Dargan / Dorgan.
For this archive, the William Penn material should therefore be treated strictly as historical place context rather than as evidence of Dorgan ancestry or land succession.
Carrigkilter Evidence List
1847 — Patrick Dargan Land Assessment
The earliest securely documented land record presently placing Patrick Dargan at Carrigkilter is the 1847 Valuation Office Tenure Book. It records Patrick in connection with land and with a house, offices, and land within the townland.
This record is important because it establishes Patrick at Carrigkilter before the published Griffith’s Valuation of 1853 and provides the first firm land anchor for the documented family.
The surviving tenure notes may contain clues about earlier leasing arrangements, but those details should not be treated as established until confirmed directly from the original archival record.
1848 — House and Office Assessment
A Valuation Office House Book dated 25 April 1848 provides the next documented step in Patrick Dargan’s Carrigkilter land history. It records Patrick at Carrigkilter and adds detail about the buildings associated with the holding.
The entry includes a piggery and cow house, showing that the holding contained working farm structures as well as the family’s residence and agricultural land.
This 1848 record is important because it strengthens the continuity between the 1847 Tenure Book and the later 1853 Griffith’s Valuation entry.
1853 — Griffith’s Valuation
Griffith’s Valuation of 1853 provides the clearest printed land record for Patrick Dargan at Carrigkilter. It records him as occupier in Carrigkilter townland, Ballintemple civil parish, Barony of Imokilly, Poor Law Union of Midleton, with Thomas G. Durdin as immediate lessor.
The valuation identifies the holding as map reference 8 on Ordnance Survey Sheet 89. That map reference is crucial because it connects Patrick’s written valuation entry to a specific place within Carrigkilter rather than to the townland only.
This record should be read together with the 1847 Tenure Book and the 1848 House Book. Together, those three sources form the strongest documented land-evidence sequence for Patrick Dargan / Dorgan at Carrigkilter.
Griffith’s Valuation Map — Holding 8
Griffith’s Valuation links Patrick Dargan’s Carrigkilter entry to map reference 8 on Ordnance Survey Sheet 89. This allows the written valuation record to be placed on a specific part of the nineteenth-century landscape.
The map is especially valuable when studied together with the valuation entry, neighboring holdings, roads, townland boundaries, and later revision evidence. It provides a geographical framework for tracing how Patrick’s holding related to the surrounding Carrigkilter community.
Map reference 8 should not by itself be treated as proof of ownership or later succession. Those questions must be answered from the written valuation and revision records associated with the holding.
1896 — Carrigkilter Farm Sale
The 1896 Carrigkilter farm sale belongs to the younger Patrick J. Dorgan, not to the earlier Patrick Dargan / Dorgan documented in the 1847–1853 valuation records. This distinction is essential when reading the land history across generations.
A notice in the Cork Examiner reported the sale of Patrick Dorgan’s interest in the Carrigkilter farm shortly before his emigration to the United States. The sale therefore marks the transition from the family’s East Cork landholding story to the Rhode Island branch.
The holding was described as 37 acres, 1 rood, and 30 perches and was sold to Mrs. Margaret Curtin of Glanturkin for £142 10s. The acreage agrees with Patrick J. Dorgan’s 19 March 1892 Land Commission vesting order and is strongly corroborated by modern Land Registry folio CK494, which records 15.1504 hectares.
Parish and Family Connections
Land records establish Patrick Dargan / Dorgan at Carrigkilter, but the family itself is reconstructed through parish and later civil records. The Ballymacoda and Ladysbridge baptismal registers document the children of Patrick and Johanna / Anne / Nancy Flynn, while later marriages connect the family to Ballybraher, Cloyne, Churchtown South, and other nearby places.
Sponsors and witnesses are especially important because they may reveal relationships that the land records do not state directly. The adult Daniel Dorgan who sponsored Mary Dorgan’s 1840 baptism is one of the strongest current clues to an earlier generation of the family.
These parish connections should be studied alongside the Carrigkilter land evidence rather than separately. Together they help place the family within a wider network of neighboring East Cork households and surnames.
Neighboring Places and Families
Carrigkilter should be studied within the wider East Cork network that includes Ballybraher, Churchtown South, Ballycatoo, Ballymacoda, Cloyne, Ballycotton, Garryvoe, Ladysbridge, and nearby townlands. These places recur in parish, land, marriage, cemetery, and later family records connected with the Dargan / Dorgan family.
Related surnames found among sponsors, witnesses, neighboring occupiers, and marriage connections can provide valuable clues. However, proximity, surname similarity, or repeated association does not by itself establish kinship.
Nearby Dargan / Dorgan households—especially those at Garryvoe, Kilmacahill, Ballybraher, and Cloyne—should therefore remain comparison families until a direct documentary link to Patrick’s Carrigkilter family is established.
Evidence and Research Cautions
The archive distinguishes carefully between confirmed evidence and research hypotheses. Patrick Dargan’s association with Carrigkilter is securely established through the 1847 Tenure Book, the 1848 House Book, and Griffith’s Valuation of 1853.
What remains unresolved is equally important. Patrick’s parentage has not been proved, the exact relationship between the Carrigkilter family and other East Cork Dargan / Dorgan households is still unknown, and the later succession history of holding 8 requires further valuation evidence.
Earlier place history, neighboring surnames, family tradition, sponsor and witness patterns, and cemetery clues may all help guide research, but they should not be presented as proven ancestry unless supported by direct or strongly converging evidence.
The adult Daniel Dorgan who sponsored Mary’s 1840 baptism is currently one of the strongest clues to Patrick’s earlier family, but his precise relationship to Patrick remains unproved.
