Mary F. Sterrett, 76, a retired legislative analyst for the Senate and an area resident for almost 40 years, died Sunday at Northern Virginia Doctors Hospital. She had emphysema.

Mrs. Sterrett moved to the Washington area in 1939. She worked for law firms until 1944, when she became clerk to the sergeant at arms of the Senate. In 1947, she became a legislative analyst. She retired in 1964.

She was born in Adrian, Mich., and moved to Springfield, Ohio, as a child. She attended Wittenberg University there.

In 1921, she married John W. Sterrett, an inspector for the old Naval Gun Factory, who died in 1968.

Mrs. Sterrett had lived in Arlington for 31 years before moving to the Washington House retirement home in Alexandria three years ago.

She was active in the Republican Women's Club of Arlington and the Arlington Hospital auxiliary. She also was a member of St. Michael's Episcopal Church of Arlington.

Survivors include a son, John P., of Walkersville, Md.; a sister, Edith Boldman, of Indianapolis, and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Mary F. Sterrett Memorial Fund, St. Michael's Episcopal Church, Arlington.
