Hi Andrew,
It's good to see you posting. We still have your book "Cush: A Civil War Memoir" listed at http://history-sites.com/books.htm#quist1 . It is an outstanding soldier's story and I hope others reading this post might try to get a copy or pick one up at the library.
I'll be monitoring your thread to see what information you garner about your Missouri ancestors.
Happy New Year!
Jim Martin
