Family Branches
Connected surnames and family lines in the Dorgan Family Archive
The Dorgan Family Archive follows the main Dorgan / Dargan line of East County Cork, Ireland, while also preserving the related family branches that appear through marriages, parish records, sponsors, witnesses, land records, census returns, photographs, and family memory.
This page introduces the surnames and family branches most often connected to the archive. Some branches are directly connected to the known Dorgan line, while others remain part of the wider East Cork research network and should be studied carefully before relationships are treated as proven.
Main Dorgan / Dargan Family Lines
Dorgan / Dargan — Core Surname Line
The Dorgan / Dargan family is the central surname line in this archive. In East Cork records, the surname appears in several forms, including Dorgan, Dargan, Dargin, and older Irish-language connections to Ó Deargáin.
The main documented research line begins with Patrick Dargan / Dorgan of Carrigkilter and Johanna / Anne / Nancy Flynn. Their family connects to Ballymacoda / Ladysbridge parish-register records, Carrigkilter land records, Griffith’s Valuation, map evidence, cemetery evidence, and later descendants in Ireland and the United States.
Because spelling varied across parish registers, valuation records, census returns, emigration records, and family documents, Dorgan and Dargan records should be studied together rather than treated as separate surnames.
Flynn — Johanna / Anne / Nancy Flynn Line
The Flynn family is one of the most important related lines in the archive because Johanna / Anne / Nancy Flynn was the wife of Patrick Dargan / Dorgan of Carrigkilter.
Her name appears in different forms across the records, including Johanna, Anne, and Nancy. These variations should be studied together, especially when comparing parish registers, children’s baptism records, family tradition, and cemetery evidence.
A possible Flynn connection points toward the Ballyandreen / Aghada / Ballycotton area, but this requires careful comparison with original parish records, sponsors, witnesses, place names, and related surnames such as Barry, Kirby, and Gorman. The Flynn line remains a key part of understanding how the Carrigkilter Dorgan family connects to the wider East Cork family network.
Hartnett — Mary Catherine Hartnett Line
The Hartnett family enters the Dorgan family story through Mary Catherine Hartnett, who married Patrick Dorgan in Cloyne on 26 November 1886.
This marriage connects the Dorgan / Dargan line of Carrigkilter with the Hartnett family of East Cork. Mary Catherine Hartnett’s family also connects to the Duhig / Doohig line, making the Hartnett branch an important part of the wider family network.
The Hartnett records should be studied alongside Cloyne parish records, marriage records, emigration records, United States census records, Rhode Island records, and later family documents. This branch helps connect the East Cork family story to the later Dorgan family history in Providence, Rhode Island.
Garde — Johanna Garde Line
The Garde family connects to the Dorgan archive through Johanna Garde, who married Michael Dorgan in Cloyne on 26 January 1869.
This marriage is important because it helps confirm Michael Dorgan as a son of Patrick Dorgan and Johanna Flynn. Through Michael and Johanna Garde, the archive follows a later Cloyne branch of the Dorgan family, including records connected to Rock Street, Cloyne.
The Garde line should be studied with Cloyne parish records, marriage witnesses, census records, related family surnames, and the later Dorgan households in Cloyne. This branch helps separate the younger Patrick Dorgan of Cloyne from the earlier Patrick Dargan / Dorgan of Carrigkilter.
Duhig / Doohig — Mary Catherine Hartnett Family Connection
The Duhig / Doohig family connects to the Dorgan archive through the Hartnett branch, especially through the family background of Mary Catherine Hartnett, who married Patrick Dorgan in Cloyne on 26 November 1886.
Because surname spellings often varied across East Cork records, Duhig and Doohig should be studied together. This family name may appear in parish registers, marriage records, baptism records, civil records, cemetery evidence, and related Hartnett family research.
The Duhig / Doohig line is important because it helps place Mary Catherine Hartnett within her wider East Cork family network and connects the Dorgan, Hartnett, and Duhig / Doohig families across parish and later family records.
Related East Cork Family Connections
Millerick — East Cork Family Connection
The Millerick family appears as part of the wider East Cork family network connected to the Dorgan / Dargan archive.
Millerick connections appear in parish-register and family records, including sponsor and marriage connections. Ned Millerick appears as a baptism sponsor in the 1844 record for Timothy Dargan / Dorgan, son of Patrick Dargan / Dorgan and Johanna Flynn. A later Johanna Millerick also connects to the Cloyne branch through her marriage to Patrick Dorgan, son of Michael Dorgan and Johanna Garde.
Because the Millerick name appears in more than one generation of records, this branch should be studied carefully with Cloyne, Ballymacoda / Ladysbridge, Carrigkilter, and related East Cork records. The Millerick family may help show how nearby families were connected through marriage, sponsorship, parish life, and local community ties.
Healy and Healey — A Confirmed Dorgan Family Branch
The Healy and Healey family is a confirmed descendant branch of the East Cork Dorgans through Mary Dorgan, daughter of Patrick Dorgan and Anne Flynn.
Mary was baptized on 13 May 1840 in Ballymacoda and Ladysbridge parish. On 10 July 1866, she married Jeremiah Healy, a farmer of Lisanley, at the Roman Catholic chapel of Churchtown. Their civil marriage registration identifies Mary’s father as Patt Dorgan, farmer, and records Michael Dorgan and Daniel Dorgan as the marriage witnesses.
Mary and Jeremiah established their family at Lisanley near Cloyne. In 1911, Mary reported that she had borne nine children and that all nine were still living. Their descendants remained in East Cork and later established Healey branches in Liverpool and Australia. The Liverpool branch was restored to the documented family history after Pauline Malone contacted William Dorgan in 2007.
Barry, Beausang, and Shinnick — Related East Cork Family Names
The Barry, Beausang, and Shinnick surnames appear as part of the wider East Cork family network surrounding the Dorgan / Dargan archive.
These names should be studied in connection with parish registers, marriage records, baptism sponsors, witnesses, land records, census returns, cemetery records, and neighboring households. They may help explain how families in Cloyne, Ballymacoda / Ladysbridge, Ballycotton, Garryvoe, Churchtown South, Ballybraher, and Carrigkilter were connected across generations.
At this stage, these surnames should be treated carefully as related East Cork research names unless a specific record proves a direct family relationship. Even when the exact relationship is not yet proven, repeated appearances of the same surnames can help identify local family networks, marriage patterns, and community connections.
O’Keeffe — Related East Cork Family Name
The O’Keeffe family appears as part of the wider East Cork family network connected to the Dorgan / Dargan archive.
O’Keeffe records should be studied alongside parish registers, marriage records, baptism sponsors, witnesses, census returns, land records, cemetery records, and nearby family names in the Cloyne, Ballymacoda / Ladysbridge, Ballycotton, Garryvoe, Churchtown South, Ballybraher, and Carrigkilter areas.
At this stage, the O’Keeffe name should be treated as a related East Cork research surname unless a specific record proves a direct connection to the known Dorgan line. Repeated appearances of the name may still help identify neighbors, witnesses, sponsors, marriage partners, and possible family connections across generations.
Later Connected Family Branches
This page follows the later Rhode Island family branch connecting William J. Dorgan Sr. and Helen Louise McIntosh, including the McIntosh, Dwyer, and Connell family connections.
McIntosh and O’Brien — Later Connected Family Branches
The McIntosh and O’Brien families appear in later branches of the family archive, especially in records connected to the United States and Rhode Island.
These families help show how the East Cork Dorgan family story continued after emigration. Records connected to these branches may include United States census records, Rhode Island state census records, marriage records, family photographs, and later family documents.
The McIntosh and O’Brien lines should be studied alongside the Dorgan family’s Providence, Rhode Island records and other later American records. These branches help connect the older East Cork evidence to the more recent family history preserved by descendants.
Research Notes and Cautions
This Family Branches page is a guide to connected surnames, not a final proof of every relationship.
Some branches are directly connected through marriage, baptism, census, emigration, or family records. Other surnames appear as part of the wider East Cork research network and should be treated as possible or related connections until supported by stronger evidence.
Because East Cork records often use spelling variations, nearby place names, repeated given names, and overlapping family surnames, each branch should be checked against original records whenever possible. Parish registers, sponsors, witnesses, land records, census returns, cemetery evidence, family photographs, and family tradition should be compared together before conclusions are treated as proven.
