Edith Timeline and Summary

The book opens on the day before Edith's wedding. Edith is asleep, so Margaret has to take responsibility for entertaining all the guests at her house.
Edith wakes up a while later and plays some piano for the guests.
We don't see Edith for the entire middle of the book because she moves to Greece with her new husband, Captain Lennox.
After both of Margaret Hale's parents die, Edith insists that Margaret move to London to live with her and her husband, now that they've moved back to England.
While Margaret is living with her, Edith tries to play matchmaker between Margaret and Edith's brother-in-law, Henry Lennox. Nothing doing, though, because Margaret decides in the end that she wants to marry Mr. Thornton from Milton.
