The former Libby Jean Hale was born and raised in Cockeysville. After graduating from Dulaney High School in 1965, she attended the University of Maryland, College Park for two years.
She was married in 1967 to Robert A. Younglove, who owns a performance coaching consulting firm.
The couple have lived for many years at Ruxton Crossing in Towson.
A music lover whose taste ranged from classical music to Broadway show tunes, Mrs. Younglove was a longtime volunteer with the Baltimore Symphony Associates and was chairman in 2012 of the Symphony Show House. She also raised money for the BSO's children's music education program.
Mrs. Younglove enjoyed spending time with her grandchildren and entertaining family and friends.
"She liked good old American home cooking," said a daughter, Rebecca F. Marsden of Towson.
Mrs. Younglove was a member of Towson Presbyterian Church, 400 W. Chesapeake Ave., Towson, where a celebration of life service will be held at 1 p.m. Sunday.
In addition to her husband and daughter, Mrs. Younglove is survived by another daughter, Elizabeth C. Conlon of Savannah, Ga.; a brother, John Hale of Baltimore; and three grandchildren.
