When looking through family pictures of relatives during various times in their life, I often find pictures in which they look like another relative. Usually it is a parent or a child, but sometimes is a grandparent.
This example is of the "Morey Chin" - at least that is what I'm calling it. I don't know who it originates from but Martha Morey (1876-1939) definitely had it. It is a relatively broad and square jaw. Her son Raymond C Wisner (1900-1977) also had it. Here are some comparison photos.
You can see on the sides of the cheeks and jaw as they get older they both have 2 lines on either side. There is yet another person in this line that appears to have the Morey Chin to me, and that would be Raymond's daughter Millie.
After looking at these pictures, to me it seems that Millie's chin might look a little more like her grandmother's. Maybe that's because it appears that Raymond has a cleft chin, while the other two do not. That makes them have a smoother, rounder tip to the chin while maintaining the squareness of the jaw that Raymond has.
