Florence Marguerite (Flop) Black, 83, the daughter, widow and mother of Army officers and a tennis player in this area in the 1930s, died of cancer Wednesday at Walter Reed Army Medical Center.

She lived in San Antonio, Tex., for 34 years before returning to this area last year to live with her son, retired Army Lt. Col. Garland C. Black Jr. of Springfield.

The daughter of a cavalry officer who won the Medal of Honor, Mrs. Black was born in Terre Haute, Ind., and grew up near Laramie, Wyo. As a child, she rode eight miles to school with members of Buffalo Bill Cody's family.

She and her husband, Brig. Gen. Garland C. Black, who died in 1951, lived in New Mexico before moving to this area in the 1930s. Mrs. Black remained in Washington during World War II, when her husband was serving as a signal officer in Europe.

In the 1930s, Mrs. Black played tennis at Chevy Chase Country Club and was captain of the women's tennis team at the Army Navy Country Club in Arlington.

After Gen. Black's retirement in 1946, the couple moved to San Antonio.

Besides her son, survivors include a daughter, Marrilyn J. Bagby of Annapolis; a sister, Thelma M. Agnew of Alexandria, seven grandchildren and 12 great-grandchildren.

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