Margaret was a mem­ber of the Io­wa Ho­li­ness As­so­ci­a­tion. She and her hus­band, song­writ­er John Har­ris, were ac­tive in ho­li­ness re­viv­als and camp meet­ings, and they were song evan­gel­ists at the 1901 Gen­er­al Ho­li­ness Con­ven­tion in Chi­ca­go, Il­li­nois. Mar­ga­ret played the or­gan to ac­com­pa­ny the du­ets she sang with her husband; the Ep­worth Or­gan and Pi­a­no Com­pa­ny pro­vid­ed an or­gan free of charge for their evan­gel­is­tic cam­paigns. In ad­di­tion, Margaret was known as an ef­fect­ive preach­er with strong mes­sag­es. Her works in­clude:

• Spiritual Songs, ed­it­or with her hus­band John & G. A. Mc­Laugh­lin (Chi­ca­go, Il­li­nois: Christ­ian Wit­ness Pub­lish­ing Com­pa­ny, cir­ca 1908)
• Glorious Gos­pel in Song (Chi­ca­go, Il­li­nois: Christ­ian Wit­ness Pub­lish­ing Co., 1910) (ed­it­or)

• Schwanz
