Hello: I am the author of the book "Disaster on the Mississippi: The Sultana Explosion, April 27, 1865" and as such I have compiled hundreds of accounts of Sultana survivors and victims. For James J. Brock, I have a ten page account entitled, "The Civil War Experiences of James J. Brock," written by Samuel D. Brock, a relative. If you wish, I could copy the pages for you and send them to you.

I also have a letter, dated April 3, 1998, from a Ms. Catherine Harper of Portland, OR, who is a relative of James J. Brook, and therefore related to you also. I can copy her letter also.
I look forward to hearing from you.
