Marion McLearn McAndrews Williams 70, a lifelong resident of Washington and a retired management analyst with the Army Material Command, died of cancer Tuesday at Providence Hospital.

Mrs. Williams, whose government service spanned 39 years, went to work for the Census Bureau in 1929. She later worked for the wages and hours division of the Department of Labor. In 1940, she transferred to the War Department and spent the war years with the Office of the Quarter-master General at Buzzard Point. She joined the Army Material Command in 1955 and retired in 1968.

She was born in her family's living quarters over the old White House stables on F Street NW, where her father was stable manager. Her early childhood memories included riding with her father on the mail wagon that delivered government agency mail to the old city Post Office at 12th Street and Pennsylvania Avenue NW.

Mrs. Williams also recalled the installation of Washington's first automatic traffic light on 16th Street NW.

She attended St. Patrick's Academy and was a member of the old St. Patrick Players.

Survivors include her husband, T. Warren, of the home in Washington; two daughters, Eileen Smith, of Lanham, and Mary Shipp, of Reading, Mass., a brother, Joseph McLearn, of Silver Spring, nine grandchildren and one great-grandchild.
