When you buy your ticket, they will give you a card which you will use later to learn about a character in the war. Don't worry about researching stuff before visiting the museum.
You can access some of this info when you get home as well with the help of your "dog tag" (card)
I would call their office and explain your need.
I recommend not researching, because you don't know who you get until you arrive. Plus, you get experience their life in the moment rather than going, "Oh yeah, that's right. He did this thing. I remember that." More "whoa" factor.
I don't know if they have that capability I would call them if not I am sure they can direct you to the proper place
You will have a choice of whom you want to follow through the war.
