The Unwelcome Mother (1916)

Ellinor, who was unofficially adopted as an orphan by 'Old Peter,' who maintained a lighthouse on a virtually deserted beach, has grown up wild and nearly silent. As she blossoms into full womanhood, she longs to know more about the world. One day a mutinous sailor swims to shore and declares that they are married, after tossing a pair of rings into the sea. He soon flees, but promises to return for her. Wealthy widower George Hudson, the richest man in the nearby port village, also falls for the fascinating, attractive young woman. He convinces her to go to a finishing school for a year and then marry him. They both find that the sea still holds a powerful pull on the soul. Which is stronger: love or the sea's magic spell?
