Marion Brown, 91, who volunteered with Army wives’ support groups in Washington, Germany and Washington state during her husband’s military career, died Feb. 13 at the Knollwood military retirement community in Washington.

She had atherosclerotic heart disease, said her son Earl V. Brown Jr.

Marion Cronin was born in Haverhill, Mass. In the 1940s, she received a bachelor’s degree from what is now Seton Hill University in Greensburg, Pa., and a master’s degree from Boston College, both in history.

She taught high school history in Massachusetts before coming to Washington, where she lived on and off for more than two decades during her husband’s career.

Her husband of 58 years, retired Army Col. Earl V. Brown Sr., died in 2004. Survivors include four children, Earl V. Brown Jr. of Riverdale, Charlotte Brown of Normal, Ill., William C. Brown of Stockton, N.J., and Ellen W. Hughes of Vancouver, Canada; a brother; three grandchildren; and two great-grandchildren.
