Mary "Maeve" O'Sullivan died on February 17, 2018, at St. Mary's Nursing Center in Leonardtown, MD, finding release after spending many years in the twilight of Alzheimer's disease. She was born August 29, 1926, to Dennis O'Mahony and Elizabeth Buckley O'Mahony in Kanturk, County Cork, Ireland. She was the youngest of six children. She had three sisters; Kay, Eilish, and Joan and two brothers; Tadhg and Seamus, all of whom preceded her in death.

She immigrated to America in the early 1960s, and she settled in the Bronx. It was there that she met her husband, Patrick O'Sullivan. They were married in 1964 and enjoyed a wonderful partnership until his death in 1997. They had two sons: Kevin O'Sullivan (wife Maureen) of East Hampton, Connecticut, and Brian O'Sullivan (wife Jennifer) of California, Maryland. She had one grandson, Ryan O'Sullivan (son of Kevin and Maureen).

Maeve is also survived by her beloved niece, Judy Sullivan, and other dear family and friends in the United States and Ireland. The family wishes to thank the staff of Cedar Lane Senior Living Community and St. Mary's Nursing and Rehabilitation Center in Maryland for their compassionate care over the past several years. Maeve loved animals and had a lifelong devotion to St. Therese of the Little Flower. She enjoyed dining out with a glass of wine in the company of family and friends. Kind in a quiet, unassuming way, Maeve had a twinkle in her eyes which her illness may have dimmed – but which can never be diminished in the memories of those who love her. She will be dearly missed.

Interment will take place on Friday, February 23, 2018 in St. Raymond's Cemetery Bronx, NY. Arrangements by Mattingley-Gardiner Funeral Home.
