Godfrey of Bouillon was only duke from 1087 to 1100, was never king of Jerusalem, and was the first and only duke of Lorraine in his family, since it was apparently granted more as a military governorship than as a fief. The first king was his brother Baldwin.
He comes from a long line of Counts of Bolougne, and his mother's father was Duke of Lower Lorraine in 1066, who holds about 6 counties in demesne or enfeoffment in the vanilla start.
To clarify, by "Edmund of Winchester", I didn't mean Earl or Count Edmund; I meant Edmund, of the house "of Winchester", son of Nobody (literally nobody, in the game), just some randomly generated courtier with no familial ties.
Now do you think this "Edmund of Winchester", and Godfrey de Bouillion are in any way comparable?
