This could be Solomon and wife Sarah Salisbury's daughter Sarah S. Salisbury. I have her estimated birth at about 1843. Her mother Sarah S. Salisbury was about 1813 VT and died after Sept 1851 possibly after the birth of their son Allen in 1851. Solomon remarries to Louisa Bartlett after her death sometime between 1851 and 1855. Is Fawn River near Colon? where Solomon resided?
Is there any more information on her tombstone?
Thank you for your help.
