Having had a look at the files myself, one thing to remember with the named characters is that they can be ferociously difficult to get. Mainly because they are only available to a single specific faction and only between certain turns.
Also you sometimes have to have just fought a battle against a specific faction.
The turns limitations can be nasty. For example both William Wallace and Joan of Arc give you just 8 turns in which to acquire them, and you need to be fighting England with battle odds of less than 1.
Naturally the less powerful ones are easier to get.
