Ruth Barnes Young, 68, a retired secretary with the National Transportation Safety Board, died Tuesday in Salt Lake City, Utah, following a stroke.

She became secretary to board member Francis H. McAdams in 1967. Soon after retiring in 1975, she moved to Salt Lake City.

Mrs. Young, a resident of Cheverly and Riverdale for 10 years, came here from her native Detroit as a young woman.

She worked as a court reporter in Prince George's County and then became a secretary at the Interior Department. While there, she was selected, "Miss Interior."

Later she worked as a secretary for entertainer Arthur Godfrey, Sen. Barry Goldwater (R-Ariz.) and senator Robert F. Kennedy (D-N.Y.) and in the office of the chairman of the Civil Aeronautics Board.

Mrs. Young was an active member of the Church of Jesus Christ of Latter-day Saints.

She is survived by her husband, Alan S. of Salt Lake City; five sons, Alan S. Jr., of Orem, Utah, Richard, of Tempe, Ariz., J. Michael, of Black Canyon, Ariz., David, of Quantico, Va., and Ernest, of Salt Lake City; a daughter, Marjorie, of Mesa, Ariz., and 14 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Diabetes Association.
