Indeed, this is a good looking man. I am guessing he is a relative, but who? I found his picture in a formal folder in a box with other Grisso information. So, I think he is from the family of my mother's father, Bert Grisso. Could he be one of my Grandpa Bert's uncles? He had many uncles.
Here we have another mystery to solve. We did find out who Carrie Plath was. We did find out that Nelle Fredrickson lived to adulthood. Something about this mystery makes me wonder if we will ever know.
