Okay, I checked my Irish Naming book which is full of history and it says it has a copyright! :(
Well, I'll just give you a general idea of what it says! :)
From 1820-1920 is when the largest amount of Irish immigrants came to the United States, during which time they were still in the grip of Anti-Gaelic laws which prohibated the use of Gaelic including Gaelic names so most of the immigrant who came to
America had standard names like
Mary,
Margaret,
Elizabeth &
Anne or anglicized versions of their favorite Irish names:
Bridget instead of
Brigid. And a lot of those new immagrants were anxious to trade their Irish sounding names in for names that sounded even less Irish like
Bridget might have changed her name to
Bertha or
Beatrice to fit is with their new surroundings.
Also Irish nicknames were often used as regular first names, peopel felt these names were closely related to the old sod in the 1920's
Annie -nn for
Anne Kitty,
Kate or
Katie - nns for
Katherine or
KathleenMaggie or
Peggy - nns for
MargaretMolly - nn for
MarySally - nn for
SarahNelly,
Nellie,
Nora - nns for
EleanorPatsy - nn for
Patricia or
Patience
Then there were the -een names that were imported from
Ireland to USA:
Kathleen, Pegeen,
Eileen,
Aileen,
Maureen,
Noreen,
Josephine,
Doreen,
Rosaleen,
Colleen (but
Colleen was only used in the USA never in
Ireland).
These names als became popular in the 1920's-1950's
Deirdre,
Keeley,
Mona,
Muriel,
Myrna,
Patricia,
Shelia,
Tracy
Here are some examples of how Gaelic names were traded in for American ones:
Aine (
Anya) became
Anna,
Anne,
HannahAislinn became
Alice,
EstherFionnuala became
Flora,
Penelope,
FlorenceGrania became
GraceMaeve became
Mabel,
Madge,
Marjorie,
MaudeSive &
Sorcha &
Saraid became
Sally,
Sarah,
SophiaOonah &
Una became
Agnes,
Winifred,
Unity
My book says these Irish-American names would not have been used in
Ireland:
Caitlin - pronounced
Kathleen in
IrelandColleen - Irish Gaelic for "girl"
Erin - Irish name for the country of
IrelandFiona - which is actually Scottish but try
Finella &
FinolaMegan - the Welsh form of
Margaret, the Irish form is Pegeen
Shannon - the name of a river in
Ireland
Sorry this is so long, I hope this helps you out!!! :)
