Marian Billups Booth (4 May 1864 – 5 January 1937), better known as Marie Booth, was the third daughter of Catherine and William Booth, the Founder of The Salvation Army.Unusually for the Victorian era, all of William and Catherine Booth's children survived into adulthood. Marie, however, had an accident at an early age that caused her to have convulsions thus making her an invalid; therefore, she was the only one of the Booth's children who did not regularly serve in The Salvation Army.
