Faith Kohl Urdahl, 79, long active in patriotic organizations, died of cancer March 17 at Georgetown University Hospital.
Born in Ilion, N.Y., she grew up in this area and attended American University. She also studied at the New York School of Interior Decorating and in Paris, France.
Although she had traveled extensively throughout the world during her marriage to a Navy officer, Mrs. Urdahl considered Washington her permanent home.
A member of the National Society of the Daughters of Founders and Patriots of America, she was in charge of its awards to service units in schools that had ROTC programs.
She also was active in the Col. John Washington Chapter of the Daughters of the American Revolution, the National Society of Magna Carta Dames, the Society of Architectural Historians, the National Trust for Historic Preservation, the Society of Genealogists of London, England, the Opera Society of Washington, the Women's Republican Club of Montgomery County and St. John's Episcopal Church at Lafayette Square.
Mrs. Urdahl had published manuscripts on her genealogical studies and had written articles for a number of magazines and publications.
She is survived by a brother, Raymond Cole, and a sister, Elizabeth Kohl Draper, both of Washington.
