I would wager Garlean Hyur are a different clan from Eorzean Hyur, neither Midlander nor Highlander (Garlander?).
There is also mention of Hyur 'tribes'. That's likely how they migrated to Eorzea, before the tribes faded away as Midlanders integrated into the cities (or formed Ala Mhigo in Highlanders case)
