Dorothy Hood Poppleton, 67, a longtime resident of the Washington area who was active in bridge and antique groups, died of cancer Thursday at the Deers Head Hospice in Salisbury, Md.

Mrs. Poppleton was born in Akron, Ohio, and studied drama at the University of Akron. She moved to the Washington area in 1938 following her marriage to Miller John Poppleton Sr., now a retired pharmacist.

While she lived here, Mrs. Poppleton was a president of the Potomac Chapter of the Questers, an antique study group. She was a life member of the Kenwood Country Club, where she played tennis, and was a life master in contract bridge. She was a member of Christ Lutheran Church in Bethesda for 25 years.

In addition to her husband, of Del Ray Beach and Ocean City, survivors include five children, Lee Ann Smith of Potomac, Penelope Miller of Rockville, Miller John Poppleton Jr. of Silver Spring, Daniel Poppleton of New York City, and Linda Locraft of Hartford, Conn.; her stepmother, Lenore Hood of Washington; one brother, Herbert Hood of Hampton, Va.; one sister, Barbara Jarosz of Fullerton, Calif., and 10 grandchildren.
