I'd like to help, but I'm afraid I can't decipher the info you have provided. Does "Nevada" mean that Mr. Blankenship was from Nevada? There was an H Company in the 2nd Battalion of each of the many infantry regiments in the US Army in WWII. However, "I. Inf" does not designate a regiment with which I am familiar. Can you provide further info, or help me better understand that which you have posted?
