Hello Alan and all,
In regards to wondering where he or I got the info about Dr. Alexius L. Middleton, besides what is handed down in the family, the following are our references and sources of info. I wrote to Terry Hambrect, M.D., about this. He is the Senior Technical Advisor to the National Museum of Civil War Medicine (14015 Manorvale Rd, Rockville, Md., 20853) and whom I got some of my info from. Here is his e-mail quoted entirely:
-------------------
"David,
My information on Dr. Alexius L. Middleton came from: Hartzler, Daniel D [1988] 'Medical Doctors of Maryland in the CSA', Originally published by Tri-State Printing, Inc, Funkstown, MD., 2nd edition. Reprinted in expanded form by Olde Soldier Books, Gaithersburg, MD, pp 58 - 59.

This is also the reference for the article about Dr. Middleton that you quoted on the "Texas in the Civil War Message Board."
I suggest you contact Mr. Hartzler to obtain his source and also to find out if he has any more information. His address is:
Daniel D. Hartzler
104 Lambert Ave
New Windsor, MD 21776

Regards, Terry"
-----------------

Speaking of Mr. Hartzler, there is no need to contact him about his source because I have his fine book, "Marylanders in the Confederacy", which lists all his sources in the rear of the book. In the rear in the list of Marylanders who served is this, on page 223: "Middleton, Alexius L. (M.D.); Asst Surg; 2nd Tx. Inf., Upper Marlburo, PG City. Ref: 1, 19, and 1690" As to those references listed:
Reference 1: National Archives, Military Records, Washington, D.C..
Reference 19: Newman, Harry Wright, comp. "Maryland Soldiers, Sailors, and Marines Who Served in the Confederate States of America." Unpublished. In the private collection of the compiler, deceased.
Reference 1690: Callcott, George H. "A History of the University of Maryland". Baltimore, Md: Maryland Historical Society, 1966.

I posted this response and the above info not to argue or anything but to show that I was not rambling on, getting his name mixed up or some sort of wondering, wishful thinking or groping in the dark. The story of my gr gr grandfather Dr. Alexius L. Middleton was not only handed down in my family and other lines descended from him, but there are sources for info on him such as listed above.
Sincerely,
David Middleton Edelen II
