Irish Origins of Darcy/Dosey

[Michael O'Hearn]

It has been claimed by some that the American immigrant Edward Dorsey of
Virginia and Maryland was desceded from an English branch of the
Anglo-Norman D'Arcy family. In 2004 is Y-DNA was found not to match that of
two sons of Sir William D'Arcy of Platten, County Meath in Ireland. (Nancy
Custer, Dorsey etc., DNA Project Results). Then what is Dorsey's actual
descent from?

I have Dorsey/Dorcey ancestry on the paternal side from County Kildare,
Ireland. Historically, this branch is believed to have migrated from County
Galway. In Connacht, there are three separate Dorcey family groupings,
reputedly one from Ui Maine in southeast Galway, one of MacDorcey in County
Leitrim, and the other in the Mayo/Sligo border area known as Partry
supposedly from an ancient tribe called Partraighe. This latter group and
related families (e.g. Coyne, Tierney, Finneran, Gormley, Kerrigan, etc.)
were anciently part of Ui Fiachra Aidhne claiming descent from Fiachra a
brother of Niall ancestor of Ui Niall. I also have Tierney ancestry on the
maternal side.

D'Arcy was also one of the fourteen Tribes of Galway making up a merchant
class of predominantly Anglo-Irish origin, Y-DNA test results confirm that
the one well documented patralineal descendant of the Irish D'Arcys of
Kiltullagh, who are descended from James Riveagh D'Arcy and of the same
supposed lineage of the Tribes of Galway D'Arcy family, was not of the
Anglo-Norman line.

Y-DNA test results at Ysearch using subjects with surnames originating from
the Partraighe region which have produced the Modal of na Partraige of the
Lakes: Corrib/Galway and Mask/Mayo. This study tests the hypothesis of
diffusion from the Shannon Estuary, the historical region settled by the Dal
Cais in the 5th century.

My Y-DNA results are only three off the Modal of na Partraighe at 41
markers, and three off the Irish Type III Modal at 41 markers tested. I
have found my paternal ancestor Daniel Haren of Ballymackea on Griffith's
Valuation for Kilmurry parish, West County Clare, Ireland. Irish Type III
is derived from the Dal Cais related to Brian Boru, the O'Brien Clan. The
Haran/Haran family group is from Ó hEagráin of County Galway which
historically has had substantial sea contact with West County Clare through
the fishing industry. They are not among the Partraighe however, and have
the same ancestral origin as O'Hara of the Cianachta originating in County
Sligo further to the north. However, this does corroborate the hypothesis
that both the Dal Cais and the Partraighe are related through diffusion from
the Shannon Estuary.

Because of close Y-DNA matches with surnames of O'Brien derivation, and
another close match with another surname located in the area of West County
Clare, I have concluded my ancestry goes back to an O'Brien son who was
adopted by a Haren family in Kilmurry about 1725 based upon the approximate
number of generations and years for a common ancestor with two of the
genetic matches.

Slightly OT but perhaps worthwhile as a entertaining diversion:

One family of Darcy of Clonuane in County Clare was
"documented" (using the term very loosely) in 1796 (copy in the FHL)
by an enthusiastic author called Darcy Burke to be connected to the
family of Darcy of Platten and thence to the Anglo-Norman family of
Darcy. From there the author proposed a vague connection of the
family to a certain Frenchwoman called Joan/Joana Darcy, whom he said
history knows as "La Pucelle" or "the Maid of Orleans". Yes, it's
Jeanne d'Arc, now known as St. Joan of Arc! A particularly fanciful
piece of creative genealogy....

If you have not seen it, there is a detailed account of the Darcy family
of Platten, co Meath in 'The Irish Genealogist' Vol 6, No 4 (November 1983)
