Jean E. Bevans, 85, an Army wife who lived at Fort Myer, Va., in the 1920s and later lived in Washington for 37 years, died of cardiac insufficiency Saturday at Heritage Hall nursing home in Leesburg, Va.

She was the widow of Stuart M. Bevans, an Army captain, who died in 1938. After she and Capt. Bevans were married in Germany, she accompanied him to posts at Fort Myer and other military installations in this country and in the Philippines.

In 1941, Mrs. Bevans returned to this area. She lived in Washington until 1978, when she moved to Waterford, Va., to live with a daughter, Eleanor B. Gomsteth. She recently moved to Heritage House in Leesburg.

Mrs. Bevans was born in Wilmington, Del., and was a charter member of the Junior League of that city. She was a member of the Army & Navy Club of Washington.

Besides Mrs. Gomsteth of Waterford, survivors include two other daughters, Marjorie B. Kent of Falls Church and Jean L. of Arlington; a sister, Sarah E. King of Rockville; a brother, Lindsay Evans of Boca Raton, Fla., eight grandchildren and five great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Heritage House, Leesburg, Va.
