Actually, kindred with the People of Wildermore is not required at all. The Survivors of Wildermore NPCs appear regardless of your reputation status with the People of Wildermore.

Basically this is the quest progression as you leave Forlaw: Dunfast (including the refugee camp) > the High Knolls (including Nona's Cave) > Balewoods (including the camp with the stable, and the cave a short ways in with the vendors, the glade in the north-east part of Balewood with the ents, the larger clearing in the north-west with another ent, etc) > the High Knolls (this time to a small village on the top of a hill, as well as Nona's Cave I think).
