Ann F. (O’Leary) Kelley, age 90, a longtime resident of Belmont, passed away peacefully on Thursday, November 5, 2026, at Bridges by EPOCH at Hingham, surrounded by the love of her devoted family.

Born in Somerville, Massachusetts, to the late Daniel and Mary O’Leary, Ann was raised in Somerville and spent her summers by the water in Quincy’s Houghs Neck neighborhood. The youngest of five children, Ann shared a particularly close bond with her sisters throughout her life.

Ann earned both her bachelor’s and master’s degrees from the former Boston State College. She began her career as an elementary school teacher and, during her teaching career, spent a short time in California.

Ann met Frederick M. “Fred” Kelley on Cape Cod while spending time with friends, beginning a partnership that would span 56 years of marriage. Together, they made their home in Belmont, where they raised their five children.

Ann devoted herself to creating a loving home for her husband and children. The birth of their youngest son, Kevin, who had special needs, brought a unique joy to Ann and Fred’s lives. Ann embraced his care with extraordinary love and devotion, while taking great pride in the lives and accomplishments of all her children.

Ann and Fred loved to travel, explore new places, and take long drives, often finding their way to a wonderful restaurant overlooking the water. They treasured these adventures and the time they spent together.

Affectionately known as “Nina” to her nine grandchildren, Ann cherished her role as a grandmother and the special relationships she shared with each of them.

Ann was the beloved wife of the late Frederick M. Kelley and the devoted mother of Michael F. Kelley and his wife Elizabeth “Lisa” of Boston; Carole A. Ellis and her husband Michael of Ashland; Suzanne M. Finn and her husband Ryan of Lexington, Virginia; Christopher D. Kelley and his wife Jeri of Billings, Montana; and the late Kevin S. Kelley.

She was the loving grandmother of Caroline, Lauren, Michael “Jack,” Charlotte, and Abby Ellis; Liam and Katherine Finn; and Andrew and Bridget Kelley.

Ann was the last surviving of five siblings. She was predeceased by her beloved sisters, Eileen Trahan and Marie Dundon, and her brothers, Rev. Gerald O’Leary and Daniel O’Leary.

Ann is also survived by several nieces, nephews, and their families, including her niece Mary Trahan, whose extraordinary dedication, love, and care meant so much to Ann and her family.

Ann will be remembered for her quick wit, infectious laughter, and the joy she found in life’s everyday moments. Her family takes comfort in knowing that she is reunited with her beloved husband, Fred, and their son, Kevin.
