The O’Mara Papers comprise predominantly business and personal records created and generated by Stephen O’Mara Junior (1884-1959) in the course of his life. Material relating to his parents, grandparents, aunts, uncles and siblings is perfunctory.

The business records cover mainly correspondence in O’Mara’s capacity as director of O’Mara’s Bacon Company and later as director of the Bacon Company of Ireland and do not encompass all operational aspects of the business. However the material provides an interesting view of the bacon industry in early 20th-century Ireland and its gradual decline from the 1930s onwards.

The personal records cover O’Mara’s political career, including his three terms as Mayor of Limerick from 1921 to 1923; the second Bond Drive to the United States, his subsequent imprisonment in 1922-1923 and the ensuing court case of 1927; and his later political involvement, particularly his role as a founding director of The Irish Press. His personal correspondence is extensive and illustrates O’Mara’s prominent role in the family as a provider of employment opportunities for the younger generations and as a generous source of financial support in times of hardship. Other material of note includes extensive correspondence and architectural drawings relating to Strand House, New Strand House and Ivy Bank House, homes of the O’Mara family.

One of the most significant aspects of the collection is material relating to the O’Brien family of Boru House, particularly the private correspondence of the novelist Kate O’Brien with her sisters, brother-in-law and nephew. The letters illuminate O’Brien’s method of writing, the creative process behind each of her novels and the ups and downs of her career as author. They also reveal her complete lack of financial acumen, her tendency to live wildly beyond her means, and her lifelong dependency on the fiscal good will of Anne and Stephen O’Mara. Of Kate O’Brien’s private life the letters reveal almost nothing, demonstrating a high degree of circumspectness and a tendency to compartmentalise various aspects of her life. The one rare exception is correspondence relating to her brief marriage and its aftermath in 1922-1925 which, while not revelatory as such, exposes a more vulnerable aspect of Kate’s personality.

The O’Brien material also contains correspondence to and from lesser known members of Kate O’Brien’s family, including her parents and her brothers Tom and Eric who died in 1918 and 1920, respectively. A small number of items relate to Michael O’Brien who died in institutional care in 1923. The identity of this individual has not been ascertained but he could possibly be Michael Alphonsus O’Brien who was born between 1888 and 1889 and is claimed to have died in infancy. Also of interest are letters from Austin Clarke to Anne O’Brien in 1916-1917 written in the early stages of the poet’s literary career, which reveal the fragility of his search for expression and sense of identity.

The material also comprises an extensive photographic record of the O’Mara and O’Brien families particularly in the 1920s and 1930s.
