By the south east corner are you sure you were up the hill? If you just go straight to the corner from the shop or wherever you wont be. If you enter the calmlands from macalania you are raised above the rest of the calmlands and you walk dowm to them by goin left, but try going right coz in that corner is where she is later on anyway, not ssure bout before you get the airship though. but i think i remember her being to the extreme west of the shop, try that.
