Mary Frances Allison was the recording studio manager at Vocalstyle for many years and did most of the editing work, in later years creating some of the Vocalstyle masters from home using a Leabarjan #5 perforator in between teaching piano. The Vocalstyle releases for September 1916 are the first to credit a hand-played roll to her, although she may have been working for them previously.

Her father, James, was born in Pennsylvania on 30 June 1843 to Scottish immigrant parents (died 20 November 1918 in Cincinnati). In 1910, he and Mary's mother, also named Mary (February 26, 1846, Indiana - 4 July 1926, Cincinnati) are the superintendent and matron of a reform school known as the Cincinnati House of Refuge - a public school for delinquent boys and girls to be sent to for vocational and academic training.

In the 1920 Census she was listed as a divorcee living at 39 Erin Ave, Cincinnati with her mother and sister, occupation "musician - piano". There is an 18 year old Mary Box listed at the address who may be her daughter.

In February 1924 she took part in a live radio broadcast from the Vocalstyle studios, in which she recorded a duet with Billy Waterworth of the new hit tune 'Somebody Else', which was then edited, perforated, and played back on roll within half an hour.In 1926, she remarried, to Phillip Sheridan Weitzel (1874-1957), who worked as a meat cutter, and disappears from the historical record until her death in 1945, of Recurrent post operative ependymoma (a form of tumour in the nervous system). She was buried on 2 July 1945 at Spring Grove Cemetery in Cincinnati.

Her Vocalstyle rolls reveal she seems to have been a versatile musician - the catalogue featuring her rolls of hymns, salon, march, jazz, blues, and foxtrot music! One press release from the era reveals she was responsible for originating the 'marimba effect' (rapid repeated notes in tremolo style) which was extremely popular in piano rolls of the time.
