Amelie de Witt Hastie, 81, a hospital volunteer for more than 60 years and a former resident of the Washington area, died Saturday at Warminster General Hospital in Warminster, Pa. after a stroke.

Mrs. Hastie was born in Norfolk. She lived in Washington for about 10 years before moving to Dowell, Calvert County, Md., in the late 1950s. She remained in Dowell until November 1980 when she moved to Southhampton, Pa., to live with a daughter, Cora Hastie Myers.

In 1978, Mrs. Hastie received an award from the Red Cross for 60 years of service as a hospital volunteer. The institutions where she worked included Walter Reed Army Hospital in Washington, Suburban Hospital in Bethesda and Calvert Memorial Hospital in Prince Frederick, Md. She was a volunteer at Warminster Hospital until the week of her death.

Mrs. Hastie's husband, retired Army Col. Frank B. Hastie, died in 1973. During his military career, Mrs. Hastie accompanied him to the various military posts where he was stationed and worked in hospitals wherever she was.

In addition to her daughter, of Southampton, Mrs. Hastie's survivors include three sons, Frank B. Jr., of Portland, Ore., the Rev. Cornelius de Witt Hastie of Jamaica Plain, Mass., and Clement A. F. Hastie of Larchmont, N.Y.; four sisters, Caroline Woodley of Courtland, Va., and Julia, Katrine, and Harriet de Witt, all of Virginia Beach; three brothers, Cornelius de Witt of Richmond, and Paul and Peter de Witt, both of Virginia Beach, and 11 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the volunteer services department at Calvert Memorial Hospital, Prince Frederick, Md. 20678, or at Warminster General Hospital, Warminster, Pa., 18974.
