Marianne H. Aaron, 90, who accompanied her husband on Army assignments around the country and in Panama, Taiwan, Japan and Germany during his more than three-decade military career, died Oct. 26 at Inova Fairfax Hospital.

She had a stroke, her daughter Christine Aaron said.

Marianne Helena O’Donoghue was born in Cardiff, Wales. She immigrated to the United States as a young girl, grew up in New York City and became a U.S. citizen in 1949. After high school, she worked as a secretary in New York.

Mrs. Aaron settled in the Washington area in the 1950s and was an Annandale resident. She volunteered in the 1970s with the Arlington Ladies, a group of women who assist families during burials at Arlington National Cemetery.

Her husband of 36 years, retired Army Lt. Gen. Harold R. Aaron, died in 1980.

Survivors include seven children, Patricia “Penny” Howk of Marietta, Ga., Dennis Aaron of Willis, Tex., Leslie Aaron and Christine Aaron, both of Reston, Jacqueline Frost of Parkland, Fla., Jeffrey Aaron of Allen, Tex., and Mark Aaron of Annandale; and five grandchildren.
