These comparisons using other people over time are very helpful and give me just the data points I need to help me make sense of my photos.  From this, it looks like the software does a good job of matching people, even as they age, so my initial assumption about who is who in the picture of 6 people is probably wrong.  Disappointing, but it's important to know.  I now have to hope I can find more photos and see if I can figure out who they are.
