Invoking Florence Nightingale in this story line is certainly due to her being well known as the preeminent pioneer of modern nursing. That includes the founding of the school of modern nursing at St. Thomas hospital in London in 1860. This story is built around that theme.
The references to women with loose morals practicing applied nursing no doubt comes from the life stories of Julia Bulette of Virginia City Nevada and Rosa May of Bodie California of that era. And there were probably 100s if not 1000s of others. They were loved and hated in their own communities. This explains the use prejudice in the story against "Kitty Albright" by the women in the wagon train.
