Which way do you prefer to see character names?

In regards to picking names from a certain time period and place that is foreign to the intended audience (historical fiction)

would you prefer to see names:

a. exactly as they were from the time period and place-

b. Anglicized versions of the exact names- (as in dropping confusing letters or combos but trying to keep the essence or root of the name)

c. Made up names that sound like they would fit but may not hold up if you knew about the area or period

I do not like novels where people have characters names such as Xichillaeltohlm (usually found in fantasy books) but sometimes that is the way historical names look to me

thanks!
