Plum Creek is originally where the Ingalls family resided. This was where Grace was born. Their farm and barn were also located there. A small creek or stream rather was not far away from there. This is where Caroline, Laura, Mary and Carrie were soaking their feet when Charles told them that this was their new home after getting the property from Lars Hanson.
When the Ingalls family lived their, many passerbys lived with them for a short time such as William O'Hara.
