Mr. Stoy returned to the Washington area in 1951 to work for the First National Bank of Arlington, Va., where he later was promoted to executive vice president. He then joined the Suburban National Bank of Virginia and was a senior vice president when he retired in 1969.

Mr. Stoy was a Mason and a member of Sharon Lodge No. 327 in McLean and also was a member of Kena Temple. He was a member of Alexandria Elks Lodge No. 758.

Survivors include his wife of 51 years, Alice, of Alexandria; two sons, Dutton G., of Springfield, Va., and Robert E., of Alexandria; a brother, Robert L., of McLean; a sister, Virginia Arnold, of Washington; and five grandchildren.
