Trudy Coulter was the wife of Joseph Coulter.
Trudy's father was a grain dealer in Minneapolis. She was pregnant with child at the time her husband convinced the local farmers to switch to corn instead of wheat. She was very worried about her husband's long journey and was consoled by Caroline that everything would be alright. When her husband was overdue, the local farmers started to believe they were cheated and upset her greatly outside Oleson's Mercantile and ran off and fell down, almost losing her baby as a result.
