Mr. and Mrs. Green

The Larsons' neighbors. Their original surname was Sjögren.

Following the death of their eldest daughter, Mr. Green decided the should immigrate to America for a new start. Due to Mrs. Green's growing paranoia over strangers, and Mr. Green's lack of farming skills, they decided it would be best to return to Sweden.

Old Jack

An elderly man who worked as a fur trapper and lived in a cave out in the wilderness. He utilizes old-fashioned traps rather than modern-style metal traps used by others.

During Changes for Kirsten Kirsten and Lars find Old Jack inside his cave while looking for shelter to pass the night; he has died, and his body is frozen. Lars speculates Old Jack's heart may have given out on him. Since he has no family, Lars suggests that they bury him in the spring after the ground thaws.
