William...
When playing historical games, William is always a very strong English name.(Pirates! Gold, Sid Meier's Pirates, Pirates and Traders)
Lothar...
After Sir Anduin Lothar. I was very heavily interested in the lore behind Warcraft I and Warcraft II. I usually use Lothar as a last name for most characters. Ironically, my World of Warcraft characters are usually undead and I name them after bones (Femur, Clavicle, Sternum, Pelvic Girdle) etc.
