I think this movie was set in pre civil war or revolutionary war time. A wealthy man wears a mask as he pretends to be his brother that is believed to be disfigured from a fire. He is smitten with a pretty young woman he once met and Either after her brother can not pay or something happens so that she is left desolate…he has her come to his place… maybe as a servant?
She is weary or this masked man not knowing he is the handsome man she had felt attracted to but over time she feels something for him but is confused. In the end he solves the mystery of who tried to kill him and IR his brother and she falls in love with him then sees who he really is. I believe it was a black and white. I believe I saw this in the late 60’s or 70’s.
