Last name: Lonergan

This most interesting surname, of Old Gaelic origin, is the Anglicized form of the Gaelic "O'Longargain", of uncertain etymology. This Irish sept inhabited north-east Thomond, that is that part of Tipperary which lay on the east side of Lough Derg, in pre-Norman times. Later the Anglo-Norman Butlers forced them southwards to Cashel and Cahir, where they have remained in considerable numbers up to the present day. The surname itself, which first appears in records in the mid 12th Century (see below), is also found in the modern idiom as "Londrigan". The chief of the sept resided at Cahir. Their importance in Irish History is due to the fact that they provided a number of leading ecclesiastics from the 12th to the 15th Century, no less than six of these being archbishops or bishops, two of Killaloe and three of Cashel. The family O'Lonergan also provided harpers to the O'Kellys of Ui Maine. They possessed a small patrimony at Ballynabanaby in south-east Galway, circa 1400. Thomas S. Lonergan (born 1861) was a notable Irish-born American poet and politician, and Anne Lonergan was an Irish nun imprisoned during the French Revolution. The family also bears a Coat of Arms which depicts on a blue chevron three gold estoiles, in chief two red arrows in saltire pointing downward. The first recorded spelling of the family name is shown to be that of Donell O'Lonergan, Archbishop of Cashell, which was dated 1152, in the "Records of the Council of Kells", during the reign of Irish Kings in opposition, disputed succession. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

Hello to all my cousins here in the U.S and those still in the old country. I'm a Lonergan through my father's mother, Florence Lonergan of Buffalo, New York. If there are other family members from that area I would like to hear from you. If there are Lonergans in Ireland who recognize my grandmother's name and city I would love to hear from you as well. The current generation doesn't know too much about our grandmother because she and my grandfather were divorced before WWII which was practially unheard of at the time. As a result she is sort of the dark secret in our family.

My father John (Jack) Lonergan was born in Emly, near Tipperary Town in 1912. I've traced the family back to the 18th Century, and all my ancestors on my father's side lived in Co. Tipperary. My father emigrated to London in the 1930's in search of work and ended up as a head chef at Fortnum & Mason (noted as grocers to the Queen) in Piccadilly, London.

Hi I am looking for info on my family. Clogheen area Co Tipp. My G Grandfather was Denis Lonergan born 1888 he had brothers - Patrick, William, Tom/Thomas, James, Phillip (who died in Kent in the army) and John. Their father was Patrick Lonergan and their mother was Ellen Lenihan(which I believe is another spelling of Lonergan). Her mother was Johanna Lenihan. Other than this I can find no trace. We have no contact with any of my Grandfather Denis' family. I have drawn a blank on this. Does this ring any bells with anyone? I live in the UK.
