Ms O’Herlihy, who was 51, died at the weekend in Marymount Hospice after a short and sudden illness.
She is survived by her husband, Dr Niall McGuinness, her mother, Kay O’Herlihy, brothers Tadgh and Fergus, and her sister, Mary.
Jo, as she was affectionately known, graduated from University College Cork with a BCL.
She was apprenticed to Tom Buckley on the Grand Parade. She became a solicitor in 1987.
She practised law with James McNulty at South Terrace, Cork, until his appointment as a judge in 2001. She then set up her own practice at Crosses Green, where she worked until shortly before her death.
In a tribute, Judge McNulty said: “She practised law with honour and integrity and with significant achievements”.
A colleague said Ms O’Herlihy will be remembered for her “wisdom, wit, and style.”
Outside of the law, she was a dog lover, a bird watcher, and a sometime horse owner; she loved nature and country life. She was also a keen fan of all sports, especially GAA and horse racing, and regularly attended the Cheltenham Festival with her husband.
Ms O’Herlihy will be buried tomorrow in St Michael’s Cemetery, Blackrock, after 11am Requiem Mass at the Missionaries of the Sacred Heart Church, Western Road.
