Margery C. Thompson, 91, of Weston died March 25 at Norwalk Hospital.

Born June 23, 1919, in Manhattan, she was daughter of the late Henrietta Spiro and Irving Callman. She was predeceased by her husband, George W. Thompson.

She volunteered as a nurse's aide for the American Red Cross during World War II and continued in that capacity throughout her life. The American Red Cross' Westport-Weston chapter in 1974 honored her for 30 years of service, and she volunteered another 36 years at blood banks in Westport, Norwalk and Wilton until last year.

After graduation from college, Thompson worked for the Board of Governors at New York Hospital. She and her husband moved from Manhattan to Weston in 1958 to raise their family. She joined Homes of Westport and Weston as a real estate agent and then bought the firm with two colleagues before selling it eventually to Coldwell Banker. She continued working for the firm until she was 85 years old and was a referring broker until her death. She was also featured in a Mini Cooper commercial filmed last October, which now airs on television and YouTube.

Survivors include a brother, Irving B. Callman of Lancaster, Pa.; a son, Peter D. Thompson of New Haven; a daughter Nancy T. Henkes of Greenwich; and two grandsons, Jeffrey R. Henkes of Greenwich, and Alexander R. Henkes of Stamford.

A service to celebrate her life will take place at 11 a.m. May 18 in Christ and Holy Trinity Episcopal Church, 55 Myrtle Ave. A private burial service was held in early April. In lieu of flowers, memorial donations may be made to the American Red Cross or to Norwalk Hospital, the Whittingham Cancer Center Research Department, c/o Richard C. Frank, 24 Stevens St., Norwalk, CT 06856.
