Augusta P. "Sukie" Cummings, 84, a founder and longtime member of the board of directors of the Arlington chapter of the American Cancer Society, died of a stroke Jan. 26 at the Jefferson retirement community in Arlington.

She served on the board for 45 years until the late 1980s and volunteered with a number of social and civic organizations in Arlington, where she lived from 1942 to 1996.

She was a member of the Northern Virginia Assistance League, the Washington Golf and Country Club and the Arlington Assembly, a sponsor of debutante balls.

In the 1950s, Mrs. Cummings did volunteer work at Marymount School in Arlington as a member of the Mother Butler Guild and received the Mother Butler medal for her service.

Mrs. Cummings, who lived in Alexandria for the last four years, was born in Portsmouth, Va., and raised in Richmond. After living in Norfolk and Baltimore, she settled in Arlington and became an active member of the Civinettes, the women's branch of the Civitan Club.

It was during those earlier years in Arlington that members of the Civinettes started the Cancer Dressing Station, which later became the local chapter of the American Cancer Society.

For her service on the board, she received its Volunteer of the Year Award in the 1960s.

Her husband, William F. Cummings Jr., died in 1989. Survivors include four children, William F. Cummings III of Winchester, Va., Nora Leigh C. Balsavage of Falls Church, Carol C. Warner of Washington and Betty C. Hickey of Alexandria; a sister; nine grandchildren; and two great-grandchildren.
