Dobbs’ father, Conway Edward Dobbs, is Justice of the Peace for County Antrim, High Sheriff for Carrickfergus in 1875, and High Sheriff for County Louth in 1882. The family spends time living in Dublin which is where Dobbs is born. She attempts to learn Irish. However, when her father dies in 1898 her mother, Sarah Mulholland, daughter of St. Clair Kelvin Mulholland Eglantine, moves the family back to Glenariff.
Dobbs’ interest in learning Irish continues and she finds it easier to learn in Donegal where the language is still spoken. Her first teacher is Hugh Flaitile. She attends the Irish College at Cloughaneely in the Donegal Gaeltacht. She brings the idea of promoting the language to the Glens of Antrim and her circle of friends. Dobbs is one of the small number of Protestant women interested in the Gaelic revival.
The “Great Feis” takes place in Antrim in 1904. Dobbs is a founding member of the Feis na nGleann committee and later a tireless literary secretary. In 1946, the Feis committee decides to honour her by presenting her with an illuminated address. It can be seen today at Portnagolan House with its stained glass windows commemorating a great Irishwoman. During her speech she says, “Ireland is a closed book to those who do not know her language. No one can know Ireland properly until one knows the language. Her treasures are hidden as a book unopened. Open the book and learn to love your language.”
Dobbs writes seven plays, published by Dundalgan Press in 1920, though only three are ever performed. The Doctor and Mrs. McAuley wins the Warden trophy for one-act plays at the Belfast festival in 1913. However, her plays are generally not a success and after 1920 she never writes another. She continues to work on historical and archaeological studies and her articles are published in the Ulster Journal of Archaeology, in a German magazine for Celtic studies, in the French Revue Celtique, and in the Irish magazine Eriu.
Roger Casement is a good friend and, although Dobbs never makes her political opinions known, she contributes to his defence costs when he is accused of treason. She also is a member of the Gaelic League and in the executive of Cumann na mBan.
She dies in Portnagalon, County Antrim, on January 2, 1962.
