Isabelle Franklin Devendorf, formerly of Nearwater Lane, Darien, died Sunday, Jan. 30, at Danbury Hospital. She was 91.

Belle, as she was known, lived in Darien for more than 70 years. She was born in Flushing, N.Y., on Dec. 13, 1919, to Lewis Betelle Franklin and Martha Dandridge Franklin. Her father was president of the Bank of New York, assistant secretary of the Treasury the United States under Woodrow Wilson, and treasure of the Episcopal Church of America for many years.

Mrs. Devendorf's mother, Martha, was a direct descendent of Martha Washington, and grew up in Virginia on one of the Dandridge family properties. As a little girl, Mrs. Devendorf spent many summers in Virginia.

Mrs. Devendorf grew up sailing competitively with her sister, Martha, at Noroton Yacht Club. She attended Chatham Hall Prep School in Virginia and then the Art Students League in New York City.

Mrs. Devendorf taught art in her home for many years, then for 20 years at King Low Heywood Thomas School.

Mrs. Devendorf was one of the co-founders of the Darien Art Show in the late '50s. She regularly showed and sold her oil paintings and watercolors at galleries, shows and retail stores in the area. She traveled to Europe, Nantucket and Maine to sketch new work during her life.

Mrs. Devendorf played years of competitive tennis and paddle tennis well into her 60s and had many trophies to show for it. She was also an avid gardener and bridge player.

Survivors include her daughter, Anne Dutson, of New Fairfield -- her caretaker later in life; her sons, Lewis of Atlanta, and David of Nantucket, Mass.; seven grandchildren and five great grandchildren.

Private interment will take place at a later date in June.
