Marion Fay

The Marquis of Kingsbury has two aristocratic children, now adults called Hampstead and Frances. The siblings fall in love with "commoners" however. The society women are is shocked that Frances would even consider marrying a clerk in the post office - a man clearly beneath her station in life -- while her brother's impending marriage is considered somewhat more acceptable. Hampstead is courting a Quaker, the Marion Fay of the title.

Trollope died shortly after Marion Fay was published, but he had already competed four additional novels and his autobiography, all of which were published after his death.
