Herminie T. Kavanagh (1876 - 1933) was an Irish writer, most known for her short stories.
Born Herminie McGibney, she became Herminie Templeton after her first marraige and Herminie Templeton Kavanagh after her second marraige (in 1905). Her second husband, Marcus Kavanagh, was a Cook County judge in Illinois.
Her best known work, Darby O'Gill and the Good People (ISBN 0966670108), was first published as a series of stories in McClure's magazine, before being published as a book in the U.S.A in 1903. A second edition, published a year before her death, was under the name "Herminie T. Kavanagh."
Her second published book, Ashes of Old Wishes and Other Darby O'Gill Tales (ISBN 0836940180), was published in 1926.
In 1959, Disney released a film based on these two books, called "Darby O'Gill and the Little People."
Mrs. Kavanagh may have moved to America, and may have written two plays "The Color Sergeant" (1903), and "Swift-Wing of the Cherokee".
