Awesome, thanks!
EDIT: One more very important thing I just noticed: it is Hugh that is the grandson of Niime (and the son of Canas, who is Niime's son). Lugh and Raigh are related to Nino but not that family.
EDIT: Oh wait, I see the confusion. Apparently Canas' wife (Hugh's mother) and Nino's mother may have been sisters, which would make Nino and Hugh cousins, although there should still be no relation between the green-haired mages and Niime except through marriage.
