George ,

Thank-you very much for your efforts! You time and energy to help are much appreciated.

The following citation in your posting was referenced in my post but I should have been more specific.
Tulane does not have this material.
In case any other researchers should see the post, please note that such a collection (see below in red) does not exist:

These letters, written in French and later translated, have been given, with their translations, to the Tulane Special Collections Department. Contact person is Dr. Wilbur Menary, Joseph Merrick Jones Hall, Tulane University Library, New Orleans, La. 70118-5682. Tel 504 865-5685, Fax 504 865-5761, e-mail: Menary@mailhost,tcs.tulane.edu. The papers are called the Cornay-Haydel Collection. (given 1998)

Again, I am very grateful for all you have done and only make this post to thank you and help others who might be mislead by the citation.
