The Lamplighter (1921)

In the absence of wealthy Malcolm Graham, his daughter secretly marries Philip Amory. Her eyesight is destroyed inadvertently by her husband; and when a baby is born, her father, not convinced that she is married, gives the child to a sailor to deliver out of the country. The sailor, however, keeps the child in his family. Cruelly mistreated, the child runs away and is taken in by an old lamplighter. Fortune brings Gertie into her grandfather's house, where she becomes companion to her blind mother. Willie Sullivan, the lamplighter's assistant, finds her father, who has been in India, and they return to America. When mother and daughter arrive to meet their ship, Gertie is rescued from a fire by the sailor who had kept her, and following Amory's reunion with his wife she becomes engaged to Willie.
