An actress and a Pfaff's regular. Clare's address appears twice in Whitman's notebooks. Clare also wrote for the New York Leader. She hosted Bohemian gatherings in her home at which Whitman was a likely attendee.
Her birth name was Jane McElhinney; she was a cousin of Paul Hamilton Hayne and the grandniece of Senator Robert Hayne.
Clare was twenty-six when the "Ellen Eyre" letter was written. She is a possible but unlikely candidate for the author of this letter.
