May God bless you and your...
If Doris (and Ken?) were in Colorado in 1958, I believe I just found a couple of pictures of her in my mother's archives. I have no idea how they knew each other, but I'm happy to forward scans should anyone want them. I'm reluctant to post them here as I'm uncertain if they actually are of the right person.

I'm so sorry for your loss.
