Regarding the character of Kraft Lawrence from Spice and Wolf, I've often wondered whether Kraft was supposed to be his familiar name or his surname. Kraft sounds more like a surname to me, but Lawrence could be either. I'm aware that in Japan, the family name is given before the familiar name, but as the story is styled more as a European medieval fantasy, it isn't so clear to me what Isuna Hasekura intended. Characters such as Norah Arendt and Eve Boland seem to have their familiar names first. Unlike Lawrence, Norah and Eve are both more commonly referred to by their first names rather than their last. My confusion is further legitimized by the third volume of the Spice and Wolf manga. In the bonus manga at the end, set in Japan, Lawrence is introduced thusly:
Young Master Lawrence of the House of Kraft.
This sidestory is obviously not canonical and not authoritative, but still serves to muddy the issue. So, is there any information that would definitively prove whether Kraft is Lawrence's familiar name or his surname?
