Marquis of Axminster

In the short story The Girl in the Train, the Marquis of Axminster is the father of Lady Elizabeth and Lord Roland. He has five daughters, and at least two sons. At the end of the story, Elizabeth accepts a proposal of marriage from George Rowland and they both comment that, doubtless, the rather impoverished Marquis would be glad that his daughter is marrying into some money.

The Marquis doesn't appear in the novel, but is mentioned.
