The Reincarnation of Nellie (Part 1)

What happens

Nellie and Percival move to New York with their twins, and Walnut Grove feels the loss, especially Harriet. Mary and Adam leave for New York too, where Adam joins a law firm, and Hester-Sue takes over running the restaurant.

Missing her daughter, Harriet adopts an orphan girl named Nancy, who looks remarkably like a young Nellie. It soon turns out the resemblance is more than skin deep. Allison Balson's Nancy makes her debut.
