Cecilia McCallum Parker Bolin, 80, a member of an old Washington family who had traveled extensively abroad, died of cancer yesterday at the Wisconsin Avenue Nursing Home.
She was born in Washington, the daughter of James McCallum, a State Department official, and Mary Sherman McCallum.
Her grandfather was John Sherman, an Ohio senator who served as secretary of State and secretary of the Treasury.
Mrs. Bolin, who had attended Holton-Arms School here, later studied at universities while staying abroad.
Her first husband was Chauncey G. Parker, a founder of the Washington brokerage firm of Auchincloss, Parker and Redpath, who was active in civic affairs here. They lived in Germany while he was assistant U.S. high commissioner there. Later, they were in Italy while he was chief of the Foreign Operations Administration's special mission there. Mr. Parker died in 1953.
In 1963, Mrs. Bolin married Luis Bolin, former information counselor at the Spanish Embassy here and an international authority on tourism. He died at their home in Malaga, Spain, in 1969.
During World War II Mrs. Bolin had been a volunteer nurse at the Newton D. Baker Army Hospital in Martinsburg, W. Va. At one time she also had been president of the board of the old Emergency Hospital here.
In 1955, she wrote a series of articles for The Washington Post on life in Russia after she had visited there as the guest of U.S. Ambassador Charles E. Bohlen and Mrs. Bohlen.
Mrs. Bolin had kept a diary since childhood. Her last entry was on Sept. 21 when she wrote, "My birthday - dammit."
She is survived by a daugher, Sherry Parker Geyelin, of Washington; a son, Chauncey G. Parker III, of Kingston, N.Y., seven grand children and one great-grandchild.
