We don't have very much information on Edgar W Bradley, the information I was able to locate was mostly from his California Pension file, filed by his Grand daughter Jennie R Bradley, on August 23 1898?

Edgar Bradley shows up on the 4th Illinois Roster as Edgar N Bradley, Pension shows Edgar H Bradley, he served as a Wagoner, holding the rank of Corporal. My roster shows Edgar enlisting in Lincoln, Illinois.
