Rosemary Stanfield, a former chief deputy clerk of the tax division of the D.C. Superior Court who later became a real estate agent for the Washington area, died Feb. 7. She was 78.

The cause was cardiac arrest, her daughter, Vicki Hammond, said, and she was pronounced dead at a hospital in McDonough, Ga.

Mrs. Stanfield, a McDonough resident, began her career in the D.C. court system as an administrative assistant in 1958. She was named chief deputy clerk of the court’s tax division in the early 1980s.

After her retirement in 1990, Mrs. Stanfield worked as a real estate agent with Town & Country Properties in Arlington County from 1997 until 2004.

Rosemary Winebrenner was born in the Allegany County, Md., community of Carlos. She moved to the Washington region in 1953 and lived in Centreville, Va. In 2004, she settled in McDonough.

She volunteered at Centreville United Methodist Church and at elementary schools in Northern Virginia.

Her husband of 42 years, James B. Stanfield, died in 1996.

Survivors include three children, Vicki Hammond of Seattle, Barry Stanfield of Aldie, Va., and Adam Stanfield of Tampa; six grandchildren; and one great-grandson.
