Gloria R. Leggin, 66, a Washington businesswoman who had been a prominent area golfer in the 1950s, died of cancer Sunday at Georgetown University Hospital.

At the time of her death, Mrs. Leggin was president of both World Search Inc., a company which does corporate trademark research, and Leggin & Associates, a firm which does accounting projects for law firms.

She and her husband, retired Army Col. Alexander Leggin, founded Leggin & Associates in the late 1960s and World Search in the mid-1970s.

Mrs. Leggin was a native of Brooklyn, N.Y. She moved to Washington in 1936 and went to work for the National Archives, first as a secretary and then as a cost accountant. During World War II, she worked for the Office of War Information and then was an administrative assistant with the Office of Strategic Services in Europe. From 1945 to 1948, she worked for the Veterans Administration.

Mrs. Leggin was the daughter of the late Wiffy Cox, a prominent area golfer who had been a pro at the Congressional Country Club. During the 1950s, Mrs. Leggin made a mark of her own in area golf circles, winning womens's championships at both the Army Navy and Congressional country clubs.

She had attended Brooklyn College and George Washington University. She was a resident of Bethesda.

Her husband died in 1979.

Mrs. Leggin's survivors include her daughter, Dorothy Anne, of Bethesda, a son, Richard Alexander, of Washington, and her mother, Genevieve Cox of Washington.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
