I have a book "Burns' Works". Index of Contents lists under the heading 'Appendix to Memoir' : "Account by Dr. Adair of a Journey with the Poet". It states under 'Appendix to Biographical sketch' - Dr. James Adair was a relative of Mrs. Dunlop's and a great admirer of the poet's genius. The beginning of the sketch reads - "Burns and I left Edinburgh together in August 1787.....etc." I wonder if there may be a connection here ?He also wrote a love song "Eppie Adair" and there are quite a few write-ups on it on the internet.
