O’MARA , Diana Lynn OβMara
August 19, 2025
At London Health Science Centre, on Tuesday August 19, 2025, Diana Lynn OβMara, at the age of 74 years. Born in Chatham in 1951, daughter of the late Louise Helen (Whaling) and Gerald McClymont.
Beloved wife of Dennis OβMara. Loving mother of Brian (Erika) OβMara and Kelly OβMara (Michael Hurren). Cherished nana of Owen, Edison and Rooney. Dear sister of Sue (Mike) Grant, Dennis McClymont, Jim (Irene) McClymont, and Bob (Rose) McClymont.
Mom lived a life of service to her family, many friends, and community. She cared deeply about women and children, and was a founding member of the Chatham-Kent Womenβs Centre, serving on the board from 1980β1987, and acting president from 1985β1986. Mom was also an entrepreneur, co-founding a court reporting business in Chatham where she worked every day until her retirement.
She was a baker, a gardener, a nana, a mom, an aunt, a friend, and so much more. She made every moment fun and magical. What most people will remember about Mom is her thoughtful and caring nature β and that she was always up for a glass of chilled white wine on the porch.
