- Biographical Information
- Her father, Salmon Portland Chase, was a prominent politician and it appears that she ran in the same social circles as FAS. FAS was invited to Kate's wedding to William Sprague in 1863 in Washington DC, but FAS was not in town so FWS wrote to FMS to share with FAS that "Miss Chase is to be married on Thursday"
