I noticed that you mentioned the family of Margaret Adair Rosson of Chattanooga, Tn. I have been trying to obtain Adair records from Vol. IX by William Playfair of "British Family Antiquity" (see previous messages) and noticed that the Chattanooga Library has a microfilm of this set of volumes which supposedly contains an Adair entry. http://www.chattanooga.govhttp://www.chattanooga.gov and click on linksto - http://www.lib.chattanooga.govhttp://www.lib.chattanooga.gov
I wonder if this library may also have information on your Adair family of Chattanooga, TN.
