Christine Peebles Abbott, 70, a retired Navy Department employe who was active in civic and church affairs, died Monday at San Giacomo Hospital in Rome, Italy, following a heart attack. She lived in Annandale and was vacationing at the time of her death.

Mrs. Abbott, who was born on a farm in Schuyler County, Mo., moved to Washington in 1930 and took a job at the Bureau of the Census. A year later, she transferred to the Navy Department, where she was became an administrative personnel officer in the old Bureau of Aeronautics. She resigned in 1941 when she married Frank Abbott.

During the years that she was raising her family, Mrs. Abbott was a president of the Parent-Teacher Association at Thomas Jefferson Junior High School and chairman of the Arlington County March of Dimes.

In 1961, she returned to the Navy Department and was an administrative officer in the Office of Legislative Affairs until her retirement in 1967.

Mrs. Abbott was a longtime member of the National City Christian Church in Washington. She was a deaconess, a member of the Official Board, chairman of the membership and evangelism committee and a leader in the Christian Women's Fellowship.

In addition to her husband, of Annandale, survivors include two daughters, Ethelyn Rose Owen of Bethesda, and Nancy Clark of Harrisburg, Pa.; one son, Paul, of Annandale; one sister, Ethelyn Kennon of Tucson, Ariz., and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Heart Fund of the American Heart Association, or to the National City Christian Church Endownment Fund, Washington.
