Okay, let me share with you the note I took on these three:
Grandma: Elizabeth 7 Pink mom (white) Pony f 11 mo
Now you know as much as I do. A very hesitant guess: Elizabeth, the grandmother of the group, is (possibly) the black-but-greying one on the left, and is (perhaps) 7. Pink, the mother, may be the one who is 7, but is probably less than 7 and more than 11 months, and is probably the white one in the middle. That would leave Pony as the fawn one on the right, who would be also female and 11 months old.
Alternatively, Elizabeth might be the 7 pink dogs, Mom might be my mom, and there might be an 11-month-old white pony in one of my pictures that I haven’t noticed yet.

The dark one, who we’ll call Elizabeth, sat in that shadow the entire time.

I wish HDR was just a little more advanced, because if you could see details in the shadows I’d absolutely love this shot.

There! Now you can see Elizabeth’s face.

Is anyone else reminded of this? Or possibly this?

The most concerned forehead-wrinkles EVER.
