Morrison's daughter Evelyn, wrote an biography about her uncle, Chronicles of Stephen Foster's Family.
Morrison's writings
In some instances, Morrison's biography conflicts with primary sources and other biographies on the life of his brother, Stephen Foster. He was selective in keeping records and correspondence that belonged to his brother, discarding items that he thought embarrassing. In his biography of Stephen he created an image of a dreamer, a naturally gifted musician, and a genius of a songwriter. He also wrote that Stephen was a devoted son to his parents. He portrayed his brother as being careless with his finances. Later biographies conflict with that of Morrison.
Civic activity
Morrison Foster served on the Allgheny County Centennial Committee as Chairman in 1887.
