From Wikipedia, the free encyclopedia

A formal Irish-language name consists of a given name and a surname, as in English. Surnames in Irish are generally patronymic in etymology, although they are no longer literal patronyms, as Icelandic names are. The form of a surname varies according to whether its bearer is male or female, and in the case of a married woman, whether she chooses to adopt her husband's surname.

An alternative traditional naming convention, not used for official purposes but generalised in Gaeltachtaí or Irish-speaking areas, (and also surviving in some rural non-gaeltacht areas) consists of the first name followed by a double patronym, usually with the father and grandfather's names. Sometimes the name of the mother or grandmother may be used instead of that of the father or grandfather.


First names

The Irish have a traditional system for naming children:[citation needed] the first son is named after the father's father, the second son after the mother's father, the third son after the father, the first daughter after the mother's mother, the second daughter after the father's mother, the third daughter after the mother. Any further children are named by the parents' choice. This has led to some spectacular names being made more common, for example there are plenty of Assumptas and Perpetuas, and many girls were named after Saints Theresa and Bernadette in the 1950s shortly after they were canonised. Many families still adhere to this way of naming children, although it is becoming less common nowadays with the influx of more secular names from the world of TV and popular music[citation needed]. Traditional names, like Gráinne, Áine and Cathal, or Irish versions of Norman names, such as Seán (from Norman French Jean), Siobhán and Sinéad, are also very common. It's possible for several cousins to have exactly the same name, e.g. Daniel Murphy, if all their fathers were brothers, and they are named after the same grandfather. To avoid confusion a pet name may be used, or a middle name e.g. Daniel Patrick may be called Dan Pat, and Daniel John may be called Danny John. Though it has been seen in older high class families[citation needed] where family records are present that the child's name can be that of an ancestor or famous person, such a thing is most prominent in the isolated families, such as the Mac Diamadas of Limerick and the Mac Gillachs of Donegal whose families have dated back to the 10th century.


A first name may be modified by an adjective to distinguish its bearer from other people with the same name. Mór ("big") and Óg ("young") are used to distinguish father and son, like English junior and senior, but are placed between the given name and the surname: Seán Óg Ó Súilleabháin corresponds to "John O'Sullivan Jr."(although anglicised versions of the name often drop the "O'" from the name).

The word Beag/Beg, meaning "little", can be used in place of Óg. This did not necessarily indicate that the younger person was small in stature, merely younger than his father. Sometimes beag would be used to imply a baby was small at birth – and premature – particularly when the baby was born less than 9 months after marriage.

Adjectives denoting hair colour may also be used, especially informally: Pádraig Rua ("red-haired Patrick"), Máire Bhán ("fair-haired Mary").

Surnames and prefixes

A male's surname generally takes the form Ó/Ua (originally "grandson") or Mac ("son") followed by the genitive case of a name, as in Ó Dónaill ("grandson of Dónall") or Mac Gearailt ("son of Gerald"). A son has the same surname as his father. A female's surname replaces Ó with (reduced from Iníon Uí - "daughter of the grandson of") and Mac with Nic (reduced from Iníon Mhic - "daughter of the son of"); in both cases the following name undergoes lenition. Thus the daughter of a man named Ó Dónaill has the surname Ní Dhónaill and the daughter of a man named Mac Gearailt has the surname Nic Gearailt. If, however, the second part of the surname begins with the letter C or G, it is not lenited after Nic: Nic Carthaigh, Nic Gearailt.[citation needed] When anglicised, the name can remain O' or Mac, regardless of gender.

If a woman marries, she may choose to take her husband's surname. In this case, Ó is replaced by Bean Uí ("wife of the grandson of") and Mac by Bean Mhic ("wife of the son of"). In both cases bean may be omitted, in which case the woman uses simply or Mhic. Again, the second part of the surname is lenited (unless it begins with C, in which case it is only lenited after ). Thus a woman marrying a man named Ó Dónaill may choose to be use Bean Uí Dhónaill or Uí Dhónaill as her surname; a woman marrying a man named Mac Gearailt may choose to use Bean Mhic Gearailt or Mhic Gearailt.

If the second part of the surname begins with a vowel, the form Ó attaches an h to it, as in Ó hUiginn (O'Higgins) or Ó hAodha (Hughes). The other forms effect no change: Ní Uiginn, (Bean) Uí Uiginn; Mac Aodha, Nic Aodha, Mhic Aodha, and so forth.

Mag is often used instead of Mac before a vowel or the silent fh. Ua is an alternative form of Ó.

Some names of Norman origin have the prefix Fitz, from Latin filius "son", such as Fitzwilliam, Fitzgerald, and so forth.

Male Female Anglicised Meaning
Ó/Ua O’ grandson/granddaughter of
Mac Nic Mc son/daughter of
Bean Uí O’ wife of the grandson of
Bean Mhic Mc wife of the son of


Many Irish surnames are concentrated in particular parts of the country and there are areas where a single surname may account for a large proportion of the population. Examples include O'Reilly/Reilly in Co. Cavan, Ryan in Co. Tipperary and East Co. Limerick and O'Sullivan in the Beara peninsula of West Cork. In such cases, the surname may also contain an additive in popular usage to differentiate one group bearing the same surname from another.

Additives are particularly common among those bearing the Ryan surname. Examples include Ryan Lacken, Ryan Luke and Ryan Doc. A man christened Thomas Ryan might be known as Tommy Doc and his family might be referred as the Docs. While the additive is not part of a person's official name, it may be used in a postal address, on an election register or in newspaper reports. In this case, Tommy Doc might be written as Thomas Ryan (D).

Like the surname, the additive is passed down from father to child. However, if a person becomes well-known by a nickname of his own, his children may take his nickname as an additive. For example, if Tommy Ryan Doc was often referred to as "Badger", his son Patrick might referred to orally as Pat Badger and written as Patrick Ryan (B).

Traditional Gaeltacht names

In Gaeltacht (Irish-speaking) areas it remains customary to use a name composed of the first name, followed by the father's name in the genitive case, followed by the name of the paternal grandfather, also in the genitive. Thus Seán Ó Cathasaigh (Sean O'Casey), son of Pól, son of Séamus, would be known to his neighbours as Seán Phóil Shéamuis. Occasionally, if the mother or grandmother was a well-known person locally, her name may be used instead of that of the father or grandfather. If the mother's name is used, then that of the maternal grandfather (or potentially grandmother) follows it, for example, Máire Sally Eoghain.

These names are not used for official purposes. Often a nickname or English version of a name is used in their composition where the person would use a standard Irish form in formal circumstances. For example, the prominent sean-nós singer Seán Mac Dhonnchadha is perhaps better known as Johnny Mhairtín Learaí.

This naming system also survives to a certain extent in rural areas outside the existing Gaeltacht. For example, it is still in use in parts of counties Londonderry and Tyrone located in the Sperrins. The system can be particularly useful for distinguishing individuals who live in the same locale, and who share a common surname but are not closely related. For example, two individuals named John McEldowney, might be known as "John Patsy Den" and "John Mary Philip" respectively.

In some cases, for example Garrett FitzGerald, "Mac Gearailt" is a translation to Irish from the Norman-derived "Fitzgerald".

There is one very interesting anglicized form of an Irish surname. (O')Hassan may have an eastern look but in Ireland it is the anglicized form of Ó hOsáin. It is to be distinguished from Ó hOisín and Ó hOiseáin (see Hession and Hishon). In County Londonderry, where it is numerous, it is spelt Hassan, Hassen, Hasson, Hassin and O'Hassan.[1][2][3][4][5][6]
