Molly Make-Believe (1916)

Molly is an irrepressible young lady who decamps from her grandmother's farm where she learns of the dire poverty with which they are threatened. Coming to the city, she seeks a position and failing to find one, hits upon the scheme of writing letters to invalids for the purpose of cheering them along the road to recovery. It so happens that her only subscriber is Carl Stanton, in whom she has already taken a violent interest. Carl is totally ignorant of the identity of his little correspondent until matters reach a climax which brings about a revelation of the fact that it is none other than Molly.
