Actually, the most literal translation would be "Close Relative", and it is interchangeably used for "Brother", "Sister", and "Cousin" as well. Sidh simply means "People", so the closest direct translation would simply be "Related People", though for the Ohn themselves, this would be a gross oversimplification. This also brings up some rather sordid questions regarding the "Ohn Wolf"...
