Lady Sylvia McCordle (Kristin Scott Thomas): Sir William's wife. Very haughty and icy, even to her own daughter.

Louisa, Lady Stockbridge (Geraldine Somerville): Wife to Lord Stockbridge and sister to Sylvia and Lavinia. Lost the privilage to marry Sir William to Sylvia, but it's pretty obvious that.

The Hon. Freddie Nesbitt (James Wilby): Husband to Mabel. Married her for her father's money. It's all gone now, and he clearly despises his wife. More than likely has had some "thing" with Isobel.

Mabel Nesbitt (Claudie Blakely): Wife to Mr. Nesbitt. Butt Monkey to everyone else.
