Interestingly

Further Googling reveals that the 1931 yearbook of the Glad Tidings Bible Institute, an early Pentecostal school located in San Francisco, contains in the back pages an advertisement from a jeweler, Henry S. Bailey, located at 133 Geary Street. This is coincidental, I suppose, to the existence of The Comforter League of Light at the same address in 1920. That was 10 years earlier. And where has Florence Crawford gone by 1930? Well, I don't know. The 1930 census does reveal a Mrs. Florence G. Crawford and husband Robert living at "Fort-Funston" in San Francisco but whether that is really the author or some other Florence G. Crawford I really can't say. More research is needed.
