Dorgan Family of East Cork, County Cork, Ireland
Dorgan Family Heritage Archive
A family-history archive bringing together records, maps, photographs, place names, and research notes for the Dorgan, Dargan, and Ó Deargáin families of East Cork, County Cork, Ireland.
The archive begins with the confirmed Carrigkilter family of Patrick Dargan / Dorgan and Johanna / Anne / Nancy Flynn, then follows related branches through Cloyne, Ballybraher, Churchtown South, Midleton, Rhode Island, and later family lines.
This site is built as a careful working archive. Some records are confirmed evidence, some are supporting context, and others are candidate or comparison records preserved for future research.
A NEW DOCUMENTARY FAMILY HISTORY
From a Farm in Carrigkilter
The Dorgan Family of East Cork: Land, Migration, and Memory
The documented story of one East Cork family begins with a small farm at Carrigkilter, an unexplained land arrangement reaching back toward 1817, and a farmer named Patrick Dargan.
From there the story moves through East Cork, across the Atlantic to Rhode Island, through successive generations—and eventually back to the places, photographs and memories from which the search began.
Chapter One is now available: Carrigkilter — The Place Before the People.

Featured Research Paths
Research Friends & Contributors
Some of the most important advances in this family history came through the generosity, local knowledge, and scholarship of people who helped preserve the Dorgan story.
Jo Cashman of Knockglass, Ladysbridge, and Pete Morrison of Churchtown South shared local family knowledge that helped reconnect the Rhode Island Dorgan family with Carrigkilter, Ballybraher, Cloyne, Garryvoe, and the wider East Cork community.
Their 2004 correspondence and Bill Dorgan’s April 2005 visit with them remain an important part of the history of this research.
Jerry Kelly and the Dorgan Name
Jerry Kelly helped resolve the historical Irish form of the family surname as Ó Deargáin and later shared remarkable research concerning the Uí Dheargáin in Ireland’s early Gaelic genealogical tradition.
His work helps explain the relationship between Dargan, Dorgan, and Ó Deargáin while keeping ancient surname history distinct from the documented Carrigkilter genealogy.
