Martha Carrington Aubrey, 77, a former music teacher at the Congressional School and at the Beauvoir School of the National Cathedral School for Girls, died of cancer Wednesday at Northern Virginia Doctors Hospital in Arlington.

Mrs. Aubrey was born in Bristol, Conn., graduated from the old New Britain Normal School and for several years was a music teacher in the public schools of Hartford, Conn., where she also was organist and choir director at a number of churches.

Following her marriage in 1929 to Raimonde Aubrey, she taught at Averett College in Danville, Va., and at Georgia State Women's College in Valdosta. In 1949, she moved to Washington and began her career at the Congressional School and at Beauvoir.

Mrs. Aubrey returned to Connecticut in 1968 and became director and accompaniest of the Quinnipiac College Choral Group in Hamden. She and the group made a number of tours to Europe, performing among other places, in The Vatican. In 1979, she retired to Arlington to be near her family.

Her marriage to Raimonde Aubrey ended in divorce.

Survivors include three children, Patricia C. Beach of Annandale, Martha Rai Buchan of West Willington, Conn., and Raymond C. Aubrey of Baltimore; a sister, Priscilla C. Kline of Silver Spring; eight grandchildren, and one great-grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
