Mary Lou was born in Allentown, PA on August 26, 1938 to the late Raymond J. Manlin and Rose T. (Hacker) Manlin and was the wife of Edwin J. Baker, with whom she celebrated 45 years of marriage last August. There was never a more devoted couple to each other.

She is also survived by multiple grandchildren and great-grandchildren. A brother, Robert W. Manlin, preceded her in death.

Mary Lou graduated from Allentown High School in 1956 followed by credits received from various educational centers. At the age of nine she discovered the joy of a life time of singing. The Lord blessed her with an exceptional voice which she used to the fullest in Northeast choirs, chorus and even a national chorus. Thru her steady church attendance, she formed the foundation of the deep and steady faith that guided her throughout life. Mary Lou with a high intelligence served as an executive secretary for many top executives over her career.

Mary Lou and her husband Ed spent 13 years of their retirement in Ocala, FL, playing golf and socializing before returning to PA in 2014.
