Mrs. Hollar lived in Darien for 16 years before moving to Brookfield, CT and then to Sun City West, Arizona. While in Darien, Mrs. Hollar belonged to Noroton Presbyterian Church where she was active in the women’s groups, the flower committee, and the bell choir. The Tres Dias weekend that she attended while at NPC made a lasting impact on her faith.

She was a long time member of Church Women United. Many hours were spent at the Darien Community Association, Darien Garden Club, and the Darien Boat Club. Her interests were horticulture, gardening, flower arranging, furniture refinishing, helping others, and entertaining. She was a lifelong student, taking many classes with respect to her interests. Margaret lived in 9 states and belonged to garden groups in all of them. While in Darien, Margaret worked in the medical and legal fields; she worked at the Darien Medical Group, Cummings & Lockwood, and GTE in Stamford.

Mrs. Hollar was most proud of starting the first Fibromyalgia Support Group at Danbury Hospital. She went on to set up an extensive network of Fibromyalgia Support groups and education in Sun City West and Phoenix, Ariz. She dedicated a large part of her life to research and support groups for those suffering from Fibromyalgia and arthritis. Mrs. Hollar struggled with Fibromyalgia from the age of 21. People from all over the United States would call Mrs. Hollar for support and advice for dealing with multiple challenges of living with Fibromyalgia Syndrome and arthritis.

Mrs. Hollar moved to The Nathaniel Witherell in Greenwich in 2009. She will probably be remembered most for her singing “God Bless America.”

A Christian burial will take place in the spring at the Noroton Presbyterian Memorial Garden.
