At the age of thirty-eight, Fanny married Alexander Van Alstyne, a blind and gifted organist and composer. He wrote the music to many of her poems which totaled at the end of her life to be nine thousand numbers. Her first major success came with the publication of "Pass Me Not, O Gentle Savior" in 1864, just before the end of the Civil War.
Pass me not, O Gentle Savior,
Hear my humble cry;
While on others Thou are smiling,
Do not pass me by.
Let me at a throne of mercy
Find a sweet relief;
Kneeling there in deep contrition
Help my unbelief.
This song became one of the most often used to appeal to sinners at revival meetings. No one can sing it without tears coming up in the eyes!
