Married in Name Only is a 1917 American silent film written by Ivan Abramson and directed by Edmund Lawrence [it], starring Gretchen Hartman, Milton Sills, and Marie Shotwell.
Madeline Francis (played by Gretchen Hartman) is just about to marry Robert Worthing (played by Milton Sills) when she learns that there is insanity in his family history (per the report of Worthing's mother, played by Marie Shotwell).
Madeline begs for the marriage to take place to avoid shame, but she is treated like a sister rather than a bride.
Madeline is left to contemplate suicide, but joy returns when Worthing finally learns he was adopted and that they can procreate without fear.
For example, the Chicago Board of Censors issued an Adults Only permit and cut, in Reel 5, a closeup of a couple embracing passionately in a bedroom.
