Middle Names and Irish Ancestors: Tradition, Myth, and Reality

Middle names are often treated as key identifiers in genealogical research, but Irish records tell a different story. Understanding how and why middle names appear—or don’t—can prevent false leads and open up more accurate paths of enquiry. In this article, Jim Ryan unpacks the traditions, exceptions, and pitfalls behind this deceptively simple detail.

Researchers will often differentiate their ancestor on the basis of a second name. He was ‘Michael Martin Murphy’ rather than plain old ‘Michael Murphy’. However, the middle name usually has little relevance when seeking a Catholic ancestor in pre-20th century Irish records. Even if an ancestor is described in a US or UK record as having a second name, you would be well advised not to put too much reliance on finding this second name in any official Irish record. Catholic children were rarely given a second name until well into the 20th century. In my own case, I am the first person in my family to have been given a second name at birth. My father, born 1921, has only one name as have all the family members in the previous generations.

This can be easily demonstrated by a search of the 1901 or 1911 census returns where a search of almost any ‘humble’ household will show that only a minority of the occupants will have a second name. An example is in Figure 1.

Nevertheless, many Irish émigrés appear in overseas records with a second name, so where might this second name have come from? There is probably no general rule about this. In areas where a particular name is very common, e.g. O’Donnell in Donegal or O’Sullivan in Kerry, people were often distinguished by a second ‘name’ which linked them to their specific family. Thus Seamus John O’Sullivan was the son of John which distinguished him from the other Seamus O’Sullivans in the area. This may have been one origin. However, this distinguishing label was often not a name. He could equally have been, for instance, Seamus ‘Óg’ (young) O’Sullivan or Seamus ‘Rua’ (Red) O’Sullivan. These names were, and still are, in common local use in areas where particular families are abundant. However, they are ‘nicknames’ rather than formal names and unlikely to have been used in any formal way.

A second possibility is that some immigrants, faced with the perceived need to fit into the local US or Canadian custom and furnish a second name, made the decision to take their ‘nickname’ as a formal part of their name. They may equally have taken some other name which had personal significance. In summary, a second name is therefore unlikely to be very useful as an identifier in Irish records.

Among Church of Ireland and Presbyterian families, and (later) in upper-class Catholic families, second names were more commonly used, particularly within wealthier families. However, often only the initial letter of the second name is given in census returns. For instance, Sylvia Jane may be listed as Sylvia J. in the census.

One particular 'middle name' custom among Church of Ireland families can also be useful to researchers. Particularly in more affluent families, the mother’s maiden name was often taken as a middle name, presumably to ensure that it would not be forgotten. In this way surnames often came to be used as personal names within particular families, and this can be a useful indicator of family lineage when conducting research.
