I am not related to the Lymans but my great-aunt's husband was Isabelle Lyman Douglas. My sister has a little child's chair that belonged to her and would be happy to send it to a direct descendent. There is a note tied to the underside of the chair that says, "This chair was given my grandmother when a little girl about 1813 or 15. After she married my grandfather Moses Lyman of Goshen, Conn in 1834. She used to sit by the fireplace in this little chair to dress and undress her babies of whom my father was the eldest. She left the chair to me. Isabelle Lyman Atwater.
I believe the grandmother to whom she refers was Mary Ann Holley (1813-1989). Isabelle Douglas Lyman lived 1867-1957.
