name this movie: boy grows up and marries lady that raised him

Does anyone know the name of the movie where a man winds up marrying a woman who took him in and raised him? The woman was the wife of a farmer who treated her very badly and they had one son. The orphan boy arrives at 9 or 10 years old and stays till early manhood (late teens), when the farmer becomes jealous of him. Ultimately the farmer dies and the orphan returns to help and eventually marries the widow who had cared for him.

Apart from this sounding a lot like Oedipus Rex, I have no idea what this might be, or why anybody would make a film containing a plot like this. Do you know if this was supposed to be a good thing in the movie?
