Kathleen T. Flannery

Kathleen “Kathy” (Tamowski) Flannery, 72, of Southington, passed away peacefully at her home on Tuesday, November 10, 2026, surrounded by family. She was the loving wife of Thomas J. Flannery for 45 years.

Kathy was born in Waterbury on September 26, 1954, to the late Raymond S. Tamowski, Sr. and Rita (Kwasniewski) Tamowski, and grew up in Naugatuck.

For fifty years Kathy ran her own bookkeeping business, work she loved too much to ever retire from. Her work gave her a deep sense of purpose. Her clients relied on her advice as much as her skill with the numbers, and she treated every one of them like a friend.

Kathy was incredibly generous. She was always thinking about other people, and it showed in the gifts she chose for them. She was also very funny. Her humor was sarcastic and perfectly timed.

A proud patriot, Kathy was a member of the American Legion Post 72 Auxiliary. Supporting veterans mattered to her, all the more because her son David serves in the U.S. Army.

Nothing came before her family. She raised two sons, Michael and David, and gained two daughters when they married, MariMeg and Katie. Then came the grandchildren, Quinn, Raymond and Kayley, who knew her as Daya or Grammy and who were the apple of her eye. She loved spending time with them above anything else.

In addition to her husband Tom, Kathy is survived by her sons, Michael Flannery and his wife MariMeg Clairwood, MD of Southington, and David Flannery and his wife Katie of Georgetown, Texas; her grandchildren, Quinn, Raymond and Kayley Flannery; her brother, Raymond S. Tamowski, Jr. and his wife Cathy of Watertown; and many nieces and nephews. She also leaves several lifelong friends, whose company she treasured immensely.

In lieu of flowers, memorial donations may be made to American Legion Kiltonic Post 72, P.O. Box 217, Southington, CT 06489.
