Cynthis: I am so glad that someone has run across this excellent collection of letters and can personally relate to them. I am working from microfilm, and I have sent the copies made from the microfilm to the Kansas Historical Society. I am sure that I have posted all of the Pelot letters, but on the off-chance that I've not, and if you are in reasonable distance of Topeka, you may want to check with them.
I think that when I complete my survey of the 1856 newspapers, I may take a shot at the 1857 papers, and if I find any more Pelot material, I will certainly alert you. If you want to contact me directly, my E-Mail is Sturkey@wctel.net.
