I've never thought that Jane and Owen look a lot alike; maybe I just never gave it any thought. When Mari & Beth were little, if people commented, "Your girls look exactly alike. They could be twins!" my answer would be, "Yeah, I know." But if someone told me that they didn't look anything alike, I'd give the same answer.
To me they were total individuals but they did and do have a strong family resemblance. Plus, I like to be agreeable.
From the angle of this picture, the family resemblance of Owen and Jane is quite evident too.
Look at their little noses, their sweet lips, the curve of their cheeks, their chins, the shape of their faces...
No doubt about it, their family.
