Mary White Pittman, 59, a lifelong area resident who was active in church and service organizations, died of cancer Sunday at the Washington Home Hospice in Washington.

She had been church secretary of All Saints Episcopal Church in Chevy Chase during the 1940s. She was a member of the altar guild and church secretary of St. Patrick's Episcopal Church in Falls Church during the 1970s.

Mrs. Pittman was a past honored queen of Bethel Chapter No. 1 of the International Order of Job's Daughters and had been a worthy matron of the Washington Centennial Chapter of the Order of the Eastern Star during the early 1950s.

She had been a troop leader and service unit chairman with the Central Fairfax Association of the Girl Scouts.

Mrs. Pittman was born in Washington and had lived in Falls Church for the past 30 years. She was a 1936 graduate of Western High School and attended Strayer Business College.

Survivors include her husband, Edgar A. Pittman, and a daughter, Melinda Pittman, both of the home; a son by a previous marriage, Phlip O. Cox, of Falls Church, another son, Andrew W. Pittman, of Denver; two brothers, Alfred L. White, of Gaithersburg, and J. Edward White, of Falls Church, and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Washington Home Hospice, to the Hospice of Northern Virginia, or to St. Patrick's Episcopal Church, Falls Church.
