Mary broke off her engagement with newspaper owner Richard Carlisle, with whom she did not get along, and who once grabbed her arm roughly during an argument. She had been engaged to Richard despite being in love with her (distant) cousin, Matthew, because she had become embroiled in a scandal and believed she had to marry him to escape notoriety. However, after she ended things with Richard, Matthew proposed to her and they became engaged.
